FLASHCARD QUESTION

Front

What is codominance?

Back

A genetic scenario where both alleles in a heterozygote are fully expressed, resulting in offspring with a phenotype that is neither dominant nor recessive.

FLASHCARD QUESTION

Front

What is incomplete dominance?

Back

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

What is the phenotypic ratio of a cross between a red flower (RR) and a speckled flower (RB)?

Back

2 red, 2 speckled.

FLASHCARD QUESTION

What is the phenotypic outcome of a cross between a black cat (BB) and a white cat (WW) under incomplete dominance?

Back

50% gray cats.

FLASHCARD QUESTION

Front

How does incomplete dominance differ from codominance?

Back

In incomplete dominance, the heterozygote shows a blend of traits, while in codominance, both traits are fully expressed.
