Patient A

Patient A is the nearly-full-term fetus of a forty year old female. Chromosomes were obtained from fetal epithelial cells acquired through amniocentesis....

1) Complete Patient A's karyotype.

2) What diagnosis would you give patient A?

3. Patient B

Patient B is a 28 year old male who is trying to identify a cause for his infertility. Chromosomes were obtained from nucleated cells in the patient's blood.....

1) Complete Patient B's karyotype.

2) What diagnosis would you give patient B?

4. Patient C

Patient C died shortly after birth, with a multitude of anomalies, including polydactyl and a cleft lip. Chromosomes were obtained from a tissue sample......

1) Complete Patient C's karyotype.

2) What diagnosis would you give patient C?

A test cross in pea plants where the purple flowers (P) are dominant over the white flowers (p).

Complete the following punnet square and then answer the questions:

PP x pp p p
P
P
