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 you see, or the physical appearance.

• Genotype
• Phenotype
• Homozygous
• Heterozygous

This is an example of ___________?

• Incomplete dominance
• Co-Dominance

What type of inheritance is shown?

• complete
• incomplete
• codominance
• sex-linked

Homozygous is when...

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