A woman is known to be carrying a rigorous recessive autosomal gene. This is possible to find out whether a cell or polar body is carrying the normal or disorder recessive. The detection method destroys the ovum.

She has opted for in vitro fertilization so the egg and sperm can be united in a test tube. To avoid having to choose a normal embryo and destroy others, she wants to be certain the egg is not carrying the mutation. It is possible to encompass the oocyte continue meiosis in a test tube.

What would you want to see in the polar body at the first meiotic division? What would you want to see in the second meiotic division? You should be capable to diagram oogenesis and segregation of the genes. Do not give probabilities, only certainly.
