Genotype for a recessive trait found on the female chromosome is b. Xh. Males have one X and one Y chromosome (XY) while females have two X chromosomes (XX). Therefore, choices a. and d. cannot be correct. Now, recessive alleles are labelled with small letters (for example, 'h') while dominant alleles are labelled with capital letters (for example, 'H'). Therefore, the only possible genotype for a recessive trait found on the female chromosome is Xh.
