What is codominance in genetics?

Back

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

Front

What are the genotypes for red, blue, and speckled flowers in codominance?

Back

Red (RR), Blue (BB), Speckled (RB).

Front

If two speckled flowers (RB) are crossed, what is the expected phenotypic ratio?

Back

1 red, 2 speckled, 1 blue.

Front

What is incomplete dominance?

Back

A genetic situation in which one allele does not completely dominate another allele, resulting in a new phenotype.

Front

What is an example of incomplete dominance?

Back

A red flower (RR) crossed with a white flower (WW) produces pink flowers (RW).

Front

What is the expected outcome of a cross between a homozygous red flower (RR) and a homozygous blue flower (BB)?

Back

All offspring will be speckled (RB).

Front

What is the definition of a phenotype?

Back

The observable physical or biochemical characteristics of an organism, as determined by both genetic makeup and environmental influences.
