Answer:
The expected proportion of F2 individuals which are homozygous recessive at both genes is 1/16
All of the F1 generation will have the normal phenotypes for both genes
There will be no homozygous individuals in the F1 generation
Most of the F2 generation will have the normal phenotypes for both genes
Explanation:
A winged hairy male is crossed with a wild type female which is homozygous
Let the allele for vestigial trait be v
allele for wild trait be w
allele for hairy trait be h
Allele for non hairy be n
The genotype of parents would be
vvhh * wwnn
Thus in F1 generation all the offsrping will have normal phenotypes for both genes
In F2 generation
vwnh * vwnh
Out of 16 offspring only one wil be homozygous recessive i,e
wwnn
Rest all 15 will have normal phenotypes.
Hence, the correct answer is
The expected proportion of F2 individuals which are homozygous recessive at both genes is 1/16
All of the F1 generation will have the normal phenotypes for both genes
There will be no homozygous individuals in the F1 generation
Most of the F2 generation will have the normal phenotypes for both genes
