Dominance and inheritance

Question 1

What is complete dominance?

Answer 1

When the dominant allele masks the recessive allele

Question 2

What is incomplete dominance?

Answer 2

Dominant allele doesn’t completely mask the recessive allele, so offspring is a combination/blend of both (blue and red make purple)

Question 3

What is codominance?

Answer 3

Both alleles are dominant and are both seen in the offspring’s phenotype (e.g., black-BB and white-WW make speckled black and white-BW)

Question 4

Extra: what blood types are dominant over O?

Answer 4

A and B, so genotypes AO and BO are phenotypes A and B while genotype AB and OO are phenotypes AB and O.
