Codominance and Incomplete Dominance Review

Front

What is Incomplete Dominance?

Back

A type of inheritance where two alleles blend together to create a new phenotype.

Front

What is Co-Dominance?

Back

A type of inheritance where both alleles are expressed equally in the phenotype.

Front

What is the expected phenotype ratio when a roan cow (RW) and a roan steer (RW) mate?

Back

1 Red : 2 Red and White : 1 White.

Front

How many alleles does an individual have for each trait?

Back

2.

Front

What is the phenotype of a grey Andalusian fowl?

Back

The phenotype is grey, resulting from the heterozygous genotype (B1B2).

Front

What is the genotype ratio for a cross between a grey fowl (B1B2) and a white fowl (B2B2)?

Back

0 B1B1 : 2 B1B2 : 2 B2B2.

Front

What does it mean if an individual is homozygous?

Back

It means they have two identical alleles for a trait.

Front

What does it mean if an individual is heterozygous?

Back

It means they have two different alleles for a trait.

Front

What is a phenotype?

Back

The observable characteristics or traits of an organism.

Front
