In humans, an X-linked disorder called coloboma iridia (a fissure in the iris) is a recessive trait. A

normal couple has an afflicted daughter. The husband sues the wife for divorce on the grounds of
infidelity. Would you find in his favor? What will be an ideal response?


ANS: Yes, the daughter would have to inherit the recessive trait from both parents and since the
husband is normal and has only one X to give, the daughter could not have gotten the recessive allele
from him`.
