Between dominant phenotype (unknown genotype) and recessive phenotype (homozygous recessive)
2
Q
What is incomplete dominance
A
Heterozygous individuals show neither of the parental phenotype

Both alleles are expressed in heterozygous but interact with each other to produce a third.

Q
What is co-dominance
A
Both alleles are dominant and expressed separately
4
Q
What are examples of co-dominance
A
AB blood group
Coat colour for cattle (ROAN cow, red and white)
Sickle cell anemia
5
Q

A
When one gene has more than two alleles
