Hello everyone here We have a question that says the woman who is a carrier of hemophilia. A married and unaffected man, which of the following is true about inheritance patterns in their offspring. X linked recessive traits such as hemophilia A are more commonly expressed in males than females because males possess only a single X. Chromosome and Females contain two x chromosomes. So males, it only takes one affected X chromosome to have the disease Women it would take two X chromosomes. So let's make opponent square for the male offspring. So we have the woman who is a carrier, so capital a lower case A. And the man who is unaffected. So lowercase a lowercase A. So we have capital. A lowercase a capital A. Or lowercase a lowercase a capital A lowercase a lowercase a lowercase a. So 50% of the sons will be Hema filic. So our answer is a thank you for watching. Bye.
