In a certain fish, fin rays (supporting structures for the fins) can be either bony or soft in adult fish. Sex linkage in a fish is similar to that in humans. What evidence would most strongly support the idea that the ray locus is on the X chromosome?
Bony ray males can pass on bony rays only to their male offspring.
Females with either bony or soft rays can reproduce, but males with soft rays cannot transfer sperm to the female.
Females with bony rays cannot pass bony rays to female offspring even if they are mating with a bony ray male.
All of the listed responses are correct.
Matings of soft ray males and bony ray females give different results from the matings of bony ray males and soft ray females.
