3.3 Biology Review

When one allele is neither dominant nor recessive over another, resulting in a blended phenotype for heterozygous offspring is considered....

• Incomplete Dominance

• Codominance

Some flowers are controlled by codominance. Red flowers (RR), blue flowers (BB) and Speckled flowers (RB).

Cross a red flower with a speckled flower. What is the phenotypic ratio?

• 2 red, 2 speckled

• 2 red, 2 blue

• 2 blue, 2 speckled

Some flowers are controlled by codominance. Red flowers (RR), blue flowers (BB) and Speckled flowers (RB).

Cross two speckled flowers.

• 1 red, 2 speckled, 1 blue

• 2 red, 2 blue

• 2 blue, 2 speckled

• 1 red, 1 speckled, 2 blue

Some flowers are controlled by codominance. Red flowers (RR), blue flowers (BB) and Speckled flowers (RB).

Cross a red flower with a blue flower.

• 1 red, 2 speckled, 1 blue

• 2 red, 2 blue

• 4 speckled

• 1 red, 1 speckled, 2 blue

When both alleles are dominant, resulting in both traits expressed in a heterozygous individual.....

• Incomplete Dominance

• Codominance

Radish color is incompletely dominant, red and white are pure breeding colors. While heterozygous are purple.

Cros a red radish with a white.

• 4 purple

• 1 red, 2 purple, 1 white

• 2 red, 2 white

• 1 red, 1 purple, 2 white

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

• Codominance

• Incomplete dominance

What type of inheritance pattern is shown here?

• Codominance
