Hello,
I want to study the inheritance of red eyes and white eyes in drosophila.
I have mated red-eyed females with white eyed males.
F1: All F1 females were white eyed and all F1 males were red-eyed.
19 white eyed females and 22 red eyed males.
I have also crossed the females and males of the F1 generation, but this is not relevant for my question.
I am trying to draw a pedigree chart for the P generation and their offspring, but there is a small problem. I know that this trait is sex-linked, and that the white eyes allele is recessive. Let R denote the red eyes allele and r the white eyes allele. Here is what I get:
Please, what is the problem?
