Question

what is genotype for a recessive trait found on the female chromosome?
○ y^h
○ x^h
○ x^h
○ y^h

Explanation:

• Females have the sex chromosome combination \(XX\). Males have \(XY\). So the trait is on the \(X\) chromosome (not \(Y\), eliminating options with \(Y\)).
• A recessive trait is represented by a lowercase letter. So \(X^{h}\) (where \(h\) is the recessive allele) is correct. \(X^{H}\) would be a dominant trait (uppercase for dominant).

Answer:

\(X^{h}\)
