Codominance

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

• Incomplete Dominance

• Co dominance

• Independent assortment

• Recessive inheritance

This type of inheritance pattern shows BOTH traits in possible offspring

• complete dominance

• incomplete dominance

• co-dominance

• dominant pattern

Codominance occurs in calico cats, which allows for the Black and Tan colors to show. What percentage of the offspring represented in this P square will be calico (black and tan spotted)?

• 25%

• 50%

• 75%

• 100%

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?

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.
