FLASHCARD QUESTION

Front

What is incomplete dominance?

Back

A genetic scenario where the phenotype of a heterozygote is intermediate between the phenotypes of the two homozygotes.

2.

FLASHCARD QUESTION

Front

What is codominance?

Back

A genetic scenario where both alleles in a heterozygote contribute equally and visibly to the phenotype.

3.

FLASHCARD QUESTION

Front

Provide an example of incomplete dominance.

Back

An example is the flower color in snapdragons, where red and white flowers produce pink offspring.

4.

FLASHCARD QUESTION

Front

Provide an example of codominance.

Back

An example is the AB blood type in humans, where both A and B alleles are expressed.

5.

FLASHCARD QUESTION

Front

How do phenotypes differ in incomplete dominance compared to codominance?

Back

In incomplete dominance, the phenotype is a blend, while in codominance, both traits are fully expressed.

6.

FLASHCARD QUESTION

Front

What is the expected phenotype ratio in a monohybrid cross exhibiting incomplete dominance?

Back

The expected phenotype ratio is 1:2:1 (one homozygous dominant, two heterozygous, one homozygous recessive).

7.

FLASHCARD QUESTION

Front

What is the expected phenotype ratio in a monohybrid cross exhibiting codominance?

Back

The expected phenotype ratio is also 1:2:1, but all phenotypes are distinct.
