Hi Everyone,
I have been trying to solve these problems with no success. Please help. Thanks in advance.
1. Determine the nature of the traits being studied (ie. whether linked or sex-linked). Explain how you reached the conclusion.
Attempted Answer:
The cross was between 5 mutant males (wym) and 5 wild type females (WYM) and another cross was between 5 wild type males (WYM) and 5 mutant females (wym).
The results achieved in the first cross was 43 wild type males, 35 wild type females, 2 females WyM and 1 female Wym.
The results achieved in the second cross was 15 male wym, 5 male WYM, 20 female WYM and 1 female Wym.
I concluded that these traits were linked on ym and YM becaues they appear together in both generations. I also concluded that they were not sex-linked traits because they were present in both generations of the male and female.
2. Show all the progenies you may obtain in the cross between 5 triple-mutant males (wym) and five triple-heterozygous females (WYM) (consider the recombination event)
Attempted Answer:
male wym X female WYM
wYm, wYm, wyM, Wym, WYm, WYm... I'm not sure that this is right.
Once again I thank you in advance for your help.
