Question

Sickle-cell anemia is a recessively inherited disease causing red blood cells to become rigid and deformed. What is the probability that a child will have sickle-cell anemia if the father has the disease and the mother is heterozygous for the disease? What is the probability that a child will be a carrier? Use a Punnett square to show your work and use the letters “A” and “a” to designate dominant and recessive alleles, respectively.

Answer 1

therefore 50%

Answer 2

i think this is it... it's been over a year since i studied biology so i am not sure what heterozygous means..

Answer 3

Heterozygous would mean one dominant and one recessive allele.

Answer 4

What you put seems perfect @Mousam :)

Answer 5
