Question

Why didn't the two sons of Queen Victoria (Alfred and Arthur) display hemophilla?

O because their father did not have the trait
O because they did not receive the recessive gene (XD) from their mother.
O because they received the dominant gene "Y" from their father
O because they are only carrying one recessive gene (b)

Answer 1

The two sons of Queen Victoria, Alfred and Arthur, did not have hemophilia because they did not receive the recessive gene from their mother.

Step-by-step explanation:

The two sons of Queen Victoria, Alfred and Arthur, did not display hemophilia because they did not receive the recessive gene (XD) from their mother. Hemophilia is an X-linked recessive disorder, which means that the gene responsible for hemophilia is located on the X chromosome. In order for a male to have hemophilia, he must inherit the recessive gene from both his mother and father. If a male inherits a dominant gene or a normal gene from his mother, he will not have hemophilia.
