Answer:
3/8
Explanation:
Martha has a widow's peak (dominant trait) and attached earlobes (recessive trait).
Martha's dad had a straight hairline (ww) and unattached earlobes (Ee, because she has the recessive alleles ee and both parents give us one allele).
This tells you that martha has a mother with at least one of both alleles dominant for widow peak and at least one recesive allele of attached earlobes
So, martha's alleles are: Ww and ee.
If she marries a man that is heterozygous for both traits (Ww and Ee) the probabilitys are
Ww Ee x Ww ee: WWEe, WwEe, wWee, and wwee
The pattern of inheritance of the offspring of a hemophiliac father would be heterozygous.
<h3>What is Hemophilia?</h3>
Hemophilia is defined as the sex–linked disorder that occurs due to an abnormality of the X chromosome.
A father that has hemophilia would be affected only on his X chromosome and can only pass it to their children making them carries.
This is because the children would inherit only one X chromosome from their father and a healthy X chromosome from their mother.
