🤓 Based on our data, we think this question is relevant for Professor Yeargain's class at UCF.
It is stated that the trait cinnabar eyes is sex-linked recessive. Thus, it is a recessive gene that is located in the sex chromosomes. If fruit flies have the same kind of sex chromosomes as that of humans, this trait is presumably in the X chromosome. That would also mean that males only need one copy of the allele while females need two in order to express the trait.
Cinnabar eyes is a sex-linked recessive characteristic in fruit flies. If a male having cinnabar eyes is crossed with a wild-type female, what percentage of the F1 males will have cinnabar eyes?
