Non-Mendelian Genetics

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

If this image were real, it would represent what type of inheritance?

• incomplete dominance
• codominance
• polygenic inheritance
• compete dominance

AB blood type is an example of what type of inheritance?

• complete dominance
• incomplete dominance
• codominance
• polygenic inheritance

A red flowered plant (RR) breeds with a White flowered plant (WW). The gene for petal color in these plants expresses incomplete dominance.  What percentage of the offspring will have pink (RW) flowers?

• 0%
• 25%
• 50%
• 100%

Aa, DD, bB, yy are all examples of

• genotypes
• phenotypes

What do you call the non-Mendelian inheritance pattern that states that neither trait is dominant and the traits appear to blend together?

• Codominance
• Incomplete dominance
• Polygenic traits

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

• Multiple alleles
• Polygenetic inheritance
• Codominance
• Incomplete 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
• Independent assortment
• Recessive inheritance

How many alleles does an individual have for each trait?

• 1
• 2
• 3
• 4
