Question

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

Explanation:

Female chromosomes are X - X. For a recessive trait on the X - chromosome, the allele is represented in lowercase (here 'h' for recessive). So the genotype should be \(X^{h}\) (since \(Y\) is male - specific, \(X^{H}\) is dominant, and \(Y^{H}\) is male - dominant - related).

Answer:

B. \(X^{h}\)
