Incomplete and Codominance

Front

What is co-dominance?

Back

Co-dominance is a type of inheritance pattern where both traits from the parents are fully expressed in the offspring.

Front

What is incomplete dominance?

Back

Incomplete dominance is a type of inheritance pattern where the offspring's phenotype is a blend of the parents' phenotypes.

Front

If a tall plant (TT) is crossed with a medium plant (TS), what fraction of the offspring will be tall?

Back

50% of the offspring will be tall.

Front

What is the phenotypic ratio when crossing a red flower (RR) with a speckled flower (RB)?

Back

The phenotypic ratio is 2 red flowers to 2 speckled flowers.

Front

What type of inheritance pattern is shown when a black chicken is crossed with a white chicken, resulting in checkered chickens?

Back

This follows a co-dominance inheritance pattern.

Front

Define complete dominance.

Back

Complete dominance is an inheritance pattern where the dominant allele completely masks the effect of the recessive allele in the phenotype.

Front

What is the result of crossing a tall plant (TT) with a short plant (SS) in terms of phenotype?

Back

The result is a medium plant (TS), demonstrating incomplete dominance.

Front

In co-dominance, how are the traits expressed in the offspring?

Back

In co-dominance, both traits are fully and separately expressed in the offspring.

Front

What is the difference between co-dominance and incomplete dominance?

Back

In co-dominance, both traits are visible, while in incomplete dominance, the traits blend to form a new phenotype.

Front

If a red flower (RR) is crossed with a blue flower (BB), what will be the offspring's phenotype?

Back

The offspring will be speckled flowers (RB), demonstrating co-dominance.
