You are studying two different mutant fish lines (A and
B). You suspect that both have mutations that cause nondisjunction for a particular chromosome, which when aneuploid results in an altered egg phenotype. You notice that all of the eggs from the A mutants have the altered phenotype. In contrast, only half the eggs laid by B mutants have the altered phenotype. If you are right and the mutants are suffering nondisjunction during meiosis, what could explain the frequency difference in egg phenotype?
