21. A sample population is 28% homozygous recessive (tt).

a. What percentage of the population has the recessive trait?

b. What is q²??

C. What is the frequency of the recessive (t) allele?

d. What is the frequency of the
(T) dominant
allele

22. Use the Hardy-Weinberg equation p + 2pq + q? = 1
a Calculate the frequency of the homozygous dominant (TT) genotype.
b. Calculate the frequency of the heterozygous (Tt) genotype.

Transpiration is the answer

The answer to this is b

The answer would be c, white eyes are homozygous recessive. in the early 1900s, morgan conducted several experiments with vinegar  flies (drosophila). one  sample revealed an anomaly: a  white-eyed, single male fly. he attempted to breed this fly with the typical red-eyed females. the offspring were all red-eyed. using flies from this new generation (brother-sister pairs)  produced some red-eyed and a few white-eyed flies. the white-eyed were all male. in later experiments, he was able to produce white-eyed females. this proved that white eyes are not lethal to either sex (ruling out a and b). since the percentage of white eyes to red eyes is so low, white eyes are not a dominant trait. it would be a recessive trait.
