A. The Hardy–Weinberg principle says that <span>genotype or allele frequencies in a population is constant from generation to generation as long as there isn't any evolutionary influences such as mutations, genetic drift, mate choice, etc. When such influences are not present, the genotype or allele frequencies will tend to an equilibrium - the number of the different alleles will be balanced. The </span>Hardy–Weinberg equation is p²+ 2pq+q²=1 where p is the dominant allele and q is the recessive allele. (p² represents homozygous dominant, 2pq represents heterozygous, and q² represents homozygous recessive.)<span>

B.
Homozygous dominant=p</span>²=0.8²=0.64
500(total number of plants in the population)×0.64(percentage of homozygous dominant)=320
It would be expected to have 320 homozygous dominant plants.

Heterozygous=2pq=2×0.8×0.2=0.32
500(total number of plants in the population)×0.32(percentage of heterozygous)=160
It would be expected to have 160 heterozygous plants.

Homozygous recessive=q²=0.2²=0.04
500(total number of plants in the population)×0.04(percentage of homozygous recessive)=20
It would be expected to have 20 homozygous recessive plants.

Violet flowers correspond to the sum of all the homozygous dominant plants and the heterozygous plants, once the violet colour is dominant over the white colour. Violet flowers=320+160=480
White flowers correspond to the homozygous recessivet plants, once the violet colour is dominant over the white colour. White plants=20

Answer;

D. The birds have different mating seasons.

Explanation;

-Different species of birds have different mating or breeding seasons. Evolution has played a role in adjusting the timing of avian(birds) breeding seasons to maximize the number of young produced. The breeding season depends on a number of factors, for example In the temperate, subarctic, and arctic zones, the overriding factor is the availability of food. This varies across all different species of birds, irrespective of other similarities they may have.
