Question

In an example of a male with hemophilia and a female carrier, what ratio of the offspring are predicted neither to carry nor to manifest the disease?

TheEntryPass · Accepted Answer

D Rationale: In a scenario involving a male with hemophilia and a female carrier, the predicted ratio of offspring that neither carry nor manifest the disease is 2 females to 1 male.

The male with hemophilia has an X-linked recessive condition, meaning he has one affected X chromosome. The female carrier has one affected X chromosome and one normal X chromosome. When their offspring are considered, the combinations result in two females who inherit the normal X from their father and one male who inherits the affected X. Thus, the other options misrepresent the ratios derived from these genetic combinations, as they do not reflect the probability of producing unaffected offspring accurately.
