Front

The blending of two traits is known as ---

Back

Front

A condition in which both alleles for a gene are expressed so that both traits are visible is known as ---

Back

Codominance

Front

What type of inheritance pattern results in a medium plant when a tall plant (TT) is crossed with a short plant (SS)?

Back

Incomplete Dominance

Front

In codominance, what are the phenotypes of red flowers (RR), blue flowers (BB), and speckled flowers (RB) when a red flower is crossed with a speckled flower?

Back

2 red, 2 speckled

Front

What is the result of crossing a red flower (RR) with a blue flower (BB) in codominance?

Back

4 speckled

Front

Define 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

Define codominance.

Back

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

Front

What is the phenotypic ratio when a red flower (RR) is crossed with a blue flower (BB) in codominance?

Back

All offspring are speckled (RB).

Front

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

Back

RR and RB.

Front

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

Back

2 red, 2 speckled.
