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.

Front

What phenotype results from crossing a red flower (RR) with a white flower (WW) in incomplete dominance?

Back

Pink flowers (RW) are produced.

Front

What percentage of offspring will be red when crossing two pink flowers (RW x RW) in incomplete dominance?

Back

25% of the offspring will be red.

Front

What genotype represents a white flower in snapdragons?

Back

WW.

Front

What genotype represents a pink flower in snapdragons?

Back

RW.

Front

In incomplete dominance, what is the phenotype of heterozygous individuals?

Back

They exhibit a blend of the dominant and recessive phenotypes.

Front

If a red flower (RR) is crossed with a pink flower (RW), what percentage of the offspring will be red?

Back

50% of the offspring will be red.

Front

What is the expected phenotype ratio from a cross between two pink snapdragons (RW x RW)?

Back

1 red : 2 pink : 1 white.

Front

What is the expected genotype ratio from a cross between two pink snapdragons (RW x RW)?

Back

1 RR : 2 RW : 1 WW.

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.
