The question is
You have crossed two Drosophila individuals that have long wings and red eyes they wild-type phenotype. In the progeney, the mutant phenotypes called curved wings and lozenge eyes appear as follows:
Females
600 long-wing, red eyes
300 curved wing, red eyes
Males:
300 long wings, red eyes
300 long wings, lozenge eyes
100 curved wings, red eyes
100 curved wings, lozenge eyes
What is the genotype of the female parent?
what is the genotype of the male parent?
What i used for my notation:
L= long wings
l=curved wings
R= red eyes
r=lozenge eyes
I already know that genotype for the wings its Ll for both parents due to the 3:1 ratio. My problem is how do i do the eyes. This problem was on my last test. And i got the eyes wrong because, the eyes are sex linked. How do i detrmine if it is sex linked or not. And after i find if its sex linked, where do i go from there.
I really need hlep on this problem. I do not know how to do genetics problem involving sex linked traits. Any one that knows anything about this topic help me out. I would really appreciate it.
Thanks
