No one in Eleanor’s family has ever had the skin condition. Bob and Eleanor have a large family. Of their eleven children, all six of their sons have normal skin, but all five of their daughters have the same skin condition as Bob.

Answer 1

Answer:

X-linked dominant

Explanation:

All of the Bob and Elenaor's sons are with normal skin, they inherited Y chromosome from the father and X from the mother.

On the other hand, all daughters have the same skin condition as Bob, they inherited one X chromosome from father and another from mother. X chromosome inherited from the father is enough for condition to appear, so it means that it is dominant and X linked.
