Which scenario below describes the life cycle of an ordinary cell thunderstorm?.

Answer:

Mendel's laws only apply to some restricted hereditary situations, that is, to those traits that are determined by a single pair of allele genes and that are found on different homologous chromosomes. Among the hereditary mechanisms that do not conform to the laws described by Mendel, the complex inheritance patterns can be mentioned: intermediate inheritance, codominance, multiple alleles and inheritance linked to sex.

Explanation:

Inheritance has patterns of transmission from parents to children such as those governed by Mendel's laws known as Mendelian inheritance, however, there are other inherited patterns known as complex inheritance patterns, among which are intermediate inheritance, codominance, multiple alleles and inheritance linked to sex. An inherited trait with an intermediate inheritance pattern expresses the two alleles that the individual possesses, but neither of them is observed as it originally is, but rather an intermediate phenotype is seen. Codominance is a situation that occurs when two different alleles are found in the genotype and both are expressed. Multiple alleles or polyalelia occur when genes have more than two allelic forms. In the case of multiple alleles, three or more alleles are present to determine a population trait. Sex-linked inheritance refers to the transmission and expression, in different sexes, of genes that are found in the non-homologous (heterologous) sector of the X chromosome inherited from the father. Two known examples are: hemophilia and color blindness determined by recessive genes in both cases.

Explanation:

The statement "selfing produces identical offspring that are clones of the parent" is true.

Selfing is the process by which an organism fertilizes its own eggs with its own sperm, resulting in offspring that have the same genetic material as the parent. Selfing (also known as self-fertilization) produces identical offspring that are genetically identical to the parent plant because it involves the fusion of gametes from the same individual. This results in a clonal population of plants.

Self-fertilizаtion (sometimes cаlled selfing) is а form of аsexuаl reproduction, but one thаt involves meiosis; аs such, there аre costs to self-fertilizаtion. The mаin cost is inbreeding depression, а reduction in offspring fitness аssociаted with recessive deleterious аlleles аcross the genome

When the body is in a shock state, the hormone released from the adrenal glands stimulates primarily alpha-1 and beta-1 receptors, but has no effects on beta-2 receptor sites is Epinephrine.

Epinephrine, also known as adrenaline, is a hormone that is produced by the adrenal glands. When the body is in a shock state, it is released into the bloodstream in order to prepare the body for a fight-or-flight response. Epinephrine primarily stimulates alpha-1 and beta-1 receptors, which can cause increased heart rate, constriction of blood vessels, and an increase in blood pressure. However, it has no effects on beta-2 receptor sites.

This is important because beta-2 receptors are found in the lungs and their stimulation can cause bronchodilation. Since epinephrine does not affect these receptors, it does not cause dilation of the bronchi and can cause respiratory distress if administered incorrectly. So therefore the hormone that is released from the adrenal glands that primarily stimulates alpha-1 and beta-1 receptors, but has no effects on beta-2 receptor sites when the body is in a shock state is Epinephrine.

The oxygen generated by photosynthesis is simply a by-product formed during the production of ATP and carbohydrates because oxygen emerges as a product that is not used by plants to further metabolic processes instead of carbohydrates and ATP.

Photosynthesis can be defined as a natural process in which plants used carbon dioxide and sun light as reactants in order to generate simple carbohydrates such as glucose and also ATP, which is the energy coin of the cells.

During photosynthetic pathways oxygen is produced but this element is not used after its production, thereby it can be considered as a byproduct of this pathway.

Therefore, with this data, we can see that photosynthesis can produce oxygen as a byproduct which is fundamental to sustaining the life of aerobic heterotrophic animals and humans because oxygen is a reactant required for cellular respiration in aerobic organisms.

After a major event at 120 generations, an allele was lost from the population. In terms of diversity, this left the population with less genetic diversity.

An allele is a variant form of a gene that appears as a result of mutation. An allele is one of the possible alternative forms of a gene that can be present at a given locus (position) on a chromosome. A gene locus refers to a specific location on a chromosome where a particular gene is found.

Genetic diversity refers to the variety of genes and alleles that exist within a population. When a population has high genetic diversity, it implies that it has a wide range of genetic variability, making it easier for the population to adapt to environmental changes. It can also protect the population from disease or predation, increase its chances of survival and persistence, and give it greater resilience against genetic drift, inbreeding, and other factors that can reduce genetic diversity.

Therefore, losing an allele from a population results in a decrease in genetic diversity, which is a disadvantage for the population.

Recombination frequency between genes L and T: 1.3%

Chromosome map:

G-L-T (12.7 map units)

L-T (1.3 map units)

d. The interference value for this data set: 91.1%

This value indicates a high degree of interference, where the occurrence of one crossover reduces the likelihood of another crossover nearby.

a. The genotypes of the parental offspring are given as:

Genotype Gg LI Tt: 621 offspring

Genotype gg litt: 1600 offspring

b. The order of the three linked genes can be determined by analyzing the genotypes of the offspring. In this case, the genotype GLItt is present, indicating that the gene L is in between the genes G and T. Therefore, the order of the linked genes is G-L-T, with gene L being in the middle.

c. To calculate the recombination frequencies between the genes, we consider the number of offspring with recombinant genotypes compared to the total number of offspring. The recombination frequencies for each pair of genes are as follows:

Recombination frequency between genes G and L: (109 + 67) / (621 + 3 + 64 + 109 + 103 + 67 + 7 + 626 + 1600) = 0.127 or 12.7%

Recombination frequency between genes L and T: (3 + 7) / (621 + 3 + 64 + 109 + 103 + 67 + 7 + 626 + 1600) = 0.013 or 1.3%

Based on these recombination frequencies, we can draw a map of the chromosome showing the order and distances between the three genes:

G--(12.7 cM)--L--(1.3 cM)--T

d. The interference value for this data set is calculated using the formula:

Interference = 1 - (observed double crossovers / expected double crossovers)

The observed double crossovers are calculated by summing the numbers of double crossover genotypes:

Observed double crossovers = (3 + 7) + (64 + 67) = 141

The expected double crossovers can be calculated by multiplying the recombination frequencies between the two pairs of genes:

Expected double crossovers = (recombination frequency between G and L) * (recombination frequency between L and T) * (total number of offspring)

Expected double crossovers = 0.127 * 0.013 * (621 + 3 + 64 + 109 + 103 + 67 + 7 + 626 + 1600) = 15.88

Plugging these values into the interference formula:

Interference = 1 - (141 / 15.88) = 0.911 or 91.1%

The interference value of 91.1% indicates a high degree of interference, meaning that the occurrence of one crossover significantly reduces the likelihood of another crossover in close proximity. It suggests the presence of factors or mechanisms that inhibit the occurrence of multiple crossovers in the region.

Thus, a cross between

AaBb and aaBb

The percent of the progeny which are likely to be agouti would be

A. a. B. b

a. Aa. aa. B. BB. Bb

a. Aa. aa. b. Bb. bb

The probability of agouti would be

1/2 (Aa) * 3/4 (BB or Bb)

= 3/8

= 37.5%

Answer:

The percentage of the progeny that are likely to be Agouti = 37.5%

Explanation:

From the given information;

An agouti mouse that is heterozygous at the albino ( A) and agouti ( B) loci ( AaBb) is mated to an albino mouse that is heterozygous at the agouti locus ( aaBb).

Agouti mouse = AaBb

If the Agouti mouse self cross; gamete needed for the crossing will be:

AB, Ab , aB, ab

Albino mouse = aaBb

If the Albino mouse self cross; gamete needed for the crossing will be:

aB, ab, aB, ab

The crossing can now be represented in a punnet square as shown below:

                AB                 Ab                 aB                    ab

aB            AaBB            AaBb             aaBB               aaBb

ab            AaBb           Aabb             aaBb               aabb

aB           AaBB            AaBb             aaBB               aaBb

ab           AaBb             Aabb              aaBb               aabb

The objective if this question is to determine the percentage of the progeny that are likely to be agouti

Let's recall that for a progeny to be agouti ; There is need for the genotype of such agouti mouse to be dominant for both traits or heterozygous for both traits.

Thus; we have;

AaBB ,  AaBb , AaBb,  AaBB, AaBb, AaBb = 6/16

The percentage of the progeny that are likely to be Agouti = 0.375
