Hemophilia is a disease caused by a gene found on the X chromosome. Therefore, it is a sex-linked disease which is caused by the recessive allele. Suppose, a man with hemophilia marries a woman who is homozygous dominant for the trait. Predict the genotype of the man. (XH = normal; Xh= hemophiliac) *
a. XH Y
b. XHXh
c. XhXh
d. Xh Y
Which statement about the pattern of inheritance for a rare dominant allele is true?
OA. Unaffected mothers have sons who are affected and daughters who are carriers.
B. Every affected person has an affected parent.
C. Affected parents do not produce affected children.
D. Unaffected fathers have sons who are affected and daughters who are carriers.
E. Unaffected parents can produce children who are affected.
In order for a male to inherit a sex-linked (X-linked) disorder, he must receive the allele from: a. his mother only. b. either his mother or father. c. his father only. d. both his mother and father.
