Question

Draw a Punnett square to show Diesha how she got sickle cell. Highlight Diesha in the Punnett. Diesha is about to marry a man who has been tested and is free of sickle cell disease and trait. Draw a Punnett for Diesha and her husband and use it to explain what their children can expect.

Answer 1

Daesh got sickle cell anemia from her parents. Both her parents must have been carriers for her to have sickle cell as demonstrated by the Punnet square below; Let as assume the dominant allele is represented by S while the recessive is represented by s.

If Daesh marries a healthy man, who is not a carrier, then their offspring will all be carriers but none will have the disorder.
