If an affected female XLX marries an unaffected male XY, what is the probability of passing the hypertrichosis gene to her offspring? Remember hypertrichosis is an X-linked dominant disease. If an affected male XLY marries an unaffected female XX, what is the probability of passing the hypertrichosis gene to his offspring?

A female who does not carry the hemophilia gene and a male hemophiliac (he has made it to his reproductive years thanks to recombinant DNA technology that has produced clotting factor for him) produce four children. Their four children (two of each sex) have normal clotting blood. One of the daughters marries a non-hemophiliac male and has three non-hem offspring (two males and one female). The other daughter of generation II marries a hemophiliac male and they have one male...

1. You have a male who displays the mutant phenotype (and thus carries the mutant allele) for the Ckesslj gene, which is located on the mitochondrial DNA. He mated with an unaffected female and has generated 3 offspring (2 females and 1 male). Draw out this pedigree, making sure you correctly draw/identify affected and unaffected individuals based on the information you have available to you. For your affected male at the beginning of the story, which of his parents is...
