Non-mendelian Genetics Review

A single gene has 3 or more alternative forms. These are called

• heterozygotes

• multiple alleles

• epistatic

• polygenic

In mice, the homozygous mice are black and white. The heterozygous mice are gray. What pattern of inheritance is expressed in fur color in mice?

• complete dominance and recessiveness
• co-dominance
• incomplete dominance
• pleiotropy

What you see, or the physical appearance.

• Genotype
• Phenotype
• Homozygous
• Heterozygous

This is an example of ___________?

• Incomplete dominance
• Co-Dominance

Homozygous is when...

• the alleles are the same
• the alleles are different
• the alleles are absent
• the alleles are present

Blood types are an example of co dominance and

• incomplete dominance
• sex linked traits
• multiple alleles
• polygenics

This is when a trait is controlled by more than one gene.

• Multiple alleles
• Polygenetic inheritance
• Codominance
• Incomplete Dominance 

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

• Incomplete Dominance

• Codominance

In mice coat color is incompletely dominant. Black and white are homozygous. Brown mice are heterozygous.

What is the genotype for a brown mouse?

• BB

• Bb

• bb

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
