Answer 4

pleiotropy

Question 5

2 deaf parents and a hearing kid

Answer 5

genetic heterogeneity

Question 6

one gene affects the expression of another (blood type)

Answer 6

epistasis

Question 7

1 allele =

Answer 7

dominant

Question 8

is sickle cell anemia a dominant or recessive disorder

Answer 8

recessive (carrier)
