All life has a common ancestor which can be traced through different lineages. Due to the fact that any new generation comes from two parents who do not share the same features. As the number of generations increases the resemblance to previous ancestors begins to minimize. For example I have brown eyes just like my mother, however, my great great grandmother had hazel eyes.

In a population that is in Hardy-Weinberg equilibrium, 49% of the population show the homozygous recessive genotype. The frequen
Kay [80]

The frequency of homozygous dominant individuals is: 42%

Hardy–Weinberg equilibrium (HWE) is a null model of the relationship between allele and genotype frequencies, both within and between generations, assuming no mutation, no migration, no selection, random mating, and infinite population size. To find the frequency of the recessive allele, we must first find the frequency of the dominant allele (p). According to the Hardy-Weinberg principle, the square root of the homozygous genotype frequency is equal to the allele frequency. The Hardy-Weinberg equation used to determine genotype frequencies is: p2 + 2pq + q2 = 1. Where 'p2' represents the frequency of the homozygous dominant genotype (AA), '2pq' the frequency of the heterozygous genotype (Aa) and 'q2' the frequency of the homozygous recessive genotype (aa).

Calculation:

q2 = 49

q= 0.7

According to Hardy–Weinberg equilibrium p + q= 1

p = 1 - q

1-0.7= 0.3

p2+ 2pq+q2=1

One can substitute the values

2pq= 2(0.3) (0.7) = 0.42

42%  is the answer.

Virty [35]

Answer:

Nuclei of gametes and somatic cells are similar to each other in its function.

Explanation:

The conclusion of the data is that the nuclei of gametes and somatic cells are similar to each other because both performs same function in the cell i.e. regulates activities of the cell. The nuclei of somatic or skin cells work efficiently in the egg cells due to similar composition and structure of nuclei that performs similar function in the cell so that's why injection of skin cell's nuclei into egg cells results the same i.e. formation of tadpoles.
