Incomplete Dominance & Codominace

Front

What is Incomplete Dominance?

Back

A genetic situation in which one allele does not completely dominate another allele, resulting in a new phenotype that is a blend of the two traits.

Front

What is Codominance?

Back

A genetic situation where both alleles in a heterozygous individual are fully expressed, resulting in offspring with a phenotype that shows both traits.

Front

What are the genotypes for Red, Blue, and Speckled flowers in codominance?

Back

Red flowers: RR, Blue flowers: BB, Speckled flowers: RB.

Front

What is the expected phenotype ratio when crossing two speckled flowers (RB x RB)?

Back

1 Red, 2 Speckled, 1 Blue.

Front

What is the expected phenotype when crossing a red flower (RR) with a blue flower (BB)?

Back

All offspring will be speckled (RB).

Front

What is the genotype for a brown mouse in incomplete dominance?

Back

Bb (heterozygous).

Front

What is the expected phenotype ratio when crossing a red radish (RR) with a purple radish (Rr)?

Back

2 Red, 2 Purple.

Front

What is the difference between Incomplete Dominance and Codominance?

Back

Incomplete Dominance results in a blend of traits, while Codominance results in both traits being fully expressed.

Front

What is a phenotype?

Back

The observable physical or biochemical characteristics of an organism, as determined by both genetic makeup and environmental influences.

Front

What is a genotype?

Back

The genetic constitution of an individual, often represented by letters (e.g., RR, Bb).
