Incomplete and codominance

When one allele is not dominant over another, resulting in a blended phenotype for heterozygous offspring is considered....

• Incomplete Dominance

• Codominance

When one allele is not dominant over the other, resulting in both traits expressed in a heterozygous individual.....

• 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

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

Cros a red radish with a purple.

• 4 purple

• 1 red, 2 purple, 1 white

• 2 red, 2 purple

• 1 red, 1 purple, 2 white

This is an example of ___________?

• Incomplete dominance
• Co-Dominance

This is an example of ___________.

•  Incomplete Dominance
•  Codominance

What type of inheritance do two alleles have if their traits blend together? 

• Incomplete Dominance
• Co-Dominance

A calico cat shows both the traits for orange fur and black fur. What kind of allele expression is this?

• Incomplete Dominance
• Co dominance

How are Incomplete Dominance and Co Dominance different than a normal Mendelian cross?

• There is no difference
• The heterozygous genotype has a unique phenotype
• There is no heterozygous genotype
• There is only one phenotype regardless of genotype.
