Incomplete Dominance Flashcard

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 color flowers do Rr snapdragons produce?

Back

Pink

Front

What are the genotypes for red, white, and speckled carnations?

Back

Red = RR, White = WW, Speckled = RW

Front

What percentage of offspring will have pink flowers when RR is crossed with WW in incomplete dominance?

Back

100%

Front

What is a recessive allele?

Back

An allele whose trait only shows up when no dominant allele is present.

Front

What is co-dominance?

Back

A type of inheritance pattern where both traits are fully expressed in the offspring.

Front

What is the genotype for a pink flower in incomplete dominance?

Back

Rr

Front

If a red flower (RR) is crossed with a white flower (rr), what is the phenotype of the offspring?

Back

All offspring will be pink (Rr).

Front

What is the phenotype of a plant with genotype WW?

Back

White flowers.

Front

In a cross between a red flower (RR) and a pink flower (Rr), what are the possible genotypes of the offspring?

Back

RR and Rr.
