Science help for me!!!!!? Please?
Refer page 505 of your A Beka Academy Biology textbook. In sex-linked heredity, the characteristic gene is found on the X(sex) chromosomes; therefore, it is inherited along with the sex of the individual. Hemophilia(Xh) is the result of a recessive sex-linked gene. A carrier has one recessive gene for hemophilia; therefore, she does not have hemophilia but can pass it on. If a normal male marries a carrier, what is the probability that they will produce a male child that will be a hemophiliac? What is the probability that they will produce a female child that will have the disease? What is the probability that a daughter will be a carrier?
