Neither Tim nor Rhoda has Duchenne muscular dystrophy, but their firstborn son does. What is the probabilitythat a second child will have the disease? What is theprobability if the second child is a boy? A girl?

is thal ui ANensn hilia is an inherited genetic disorder linked to the nosome that results in ineffective blood clotting when a blood is damaged. The most common type, hemophilia A, occurs 5000 male births. Any male who carries the gene will express enotype. Hemophilia is extremely rare in women. Parents Carrler female Normal male couple wish to have children. The woman knows she a rrier for hemophilia. The man is not a hemophiliac.

John has alkaptonuria; it "runs in the family". John and his grandmother are both homozygous for alkaptonuria. John's grandmother has two brothers and a sister. One of the brothers had alkaptonuria and his daughter is John's mother. Based on this information, John's parents are:

a boy is colorblind

Patient A's History Patient A is the nearly-full-term fetus of a forty year old female. Chromosomes were obtained from fetal epithelial cells acquired through amniocentesis. Patient A's Karyotype See attached picture 1. Using the correct notation for interpreting karyotypes, give your diagnosis for the conditions of each patient.
