A phenotypically normal man with no family history of either disease is married to a phenotypic ally normal woman. whose father has hemophilia A and mother is colorblind. If this couple has a son.. Part A what is the probability that he will have neither hemophilia nor colorblindness? Express your answer as a percent. Do not include the percent symbol, which should already be part of the answer box.

Explanation / Answer

since mentioned that mother has colorblindness(HHcc) and father is suffering from hemophilia A (hhCC) ; where H and C are dominant normal traits and h &c are recessive mutants.

H_C_carrier

this will give the genetic make up of the female. i.e. HhCc when she marries a normal male HHCC

thus, fathers gamete will be HC

mothers gamete will be HC/hc/Hc/hC

but since no gene coming from father is mutant thus, all progeny daughetrs as well as sons will be normal i.e. %age of suffering from hemophilia A and colorblindness is 0.

H_C_carrier
