Biology Question?

Since the genes are located on different chromosomes, there will be no linkage, and the alleles will assort independently.

W = wild type, dominant, long wings
w = recessive, vestigial wings
H = wild type, dominant, hairless body
h = recessive, hairy body

vestigial-winged hairy male x normal female
wwhh x WWHH
F1 progeny all genotype WwHh
all phenotypically normal (long wings, hairless body)

WwHh x WwHh
F2 progeny
genotypes                           phenotypes
1 WWHH                             normal
2 WWHh                             normal
1 WWhh                              long wings, hairy body
2 WwHH                             normal
4 WwHh                              normal
2 Wwhh                               long wings, hairy body
1 ww HH                             vestigial wings, hairless body
2 wwHh                               vestigial wings, hairless body
1 wwhh                                vestigial wings, hairy body

out of 16 individuals you would expect
9 normal
3 long wings, hairy body
3 vestigial wings, hairless body
1 vestigial wings, hairy body

So the ratio is 9:3:3:1.
This is the classic Mendelian dihybrid ratio.

Dominant Traits: Long wings, (L) Hairless body (H)
Recessive Traits: Vestigial Wings, (l) Hairy body (h)

12 hairless:4 hairy - 12 Long winged:4 vestigial

F2:
9 Longwinged  & Hairless
3 Longwinged & Hairy
3 Vestigial Wings & Hairless
1 Vestigial Wings & Hairy


That is the answer and how to solve it. Hope it helped.
