Question 1

What are the three types of dominance

Answer 1

-Complete dominance
-Incomplete dominance
-Codominance

Question 2

Define complete dominance

Answer 2

-A state in which both alleles of a heterozygous individual are fully expressed in the phenotype

Question 3

Define incomplete dominance

Answer 3

Its when a heterozygous individual has a phenotype that is a mix of the two traits from the homozygous parents

Question 4

Define codominance

Answer 4

Its when two alleles are completely dominant

Question 5

Contrast complete dominance, incomplete dominance and codominance

Answer 5

In complete dominance, only one allele in the genotype is seen in the phenotype.
In codominance, both alleles in the genotype are seen in the phenotype.
In incomplete dominance, a mixture of the alleles in the genotype is seen in the phenotype

Question 6

Answer 6

The heterozygous phenotype is a blend of the two homozygous phenotypes
