If you crossed flies heterozygous for the Cy allele,what surviving genotypes would you find in the F₂ generation? A)Cy⁺/Cy⁺ B)Cy/Cy⁺ C)Cy⁺/Cy⁺ and Cy/Cy⁺ D)Cy⁺/Cy⁺,Cy/Cy⁺,and Cy/Cy

Question

Quizplus · Accepted Answer

When crossing heterozygous flies for the Cy allele, there are two possible genotypes in the parent generation: Cy⁺/Cy⁺ and Cy/Cy⁺. When these parents are crossed, the possible genotypes in the F₂ generation are Cy⁺/Cy⁺, Cy⁺/Cy⁺ and Cy/Cy⁺. Cy/Cy can also be a possible genotype in the F₂ generation, but it was not given as an option. Therefore, the best choice is C.
