Non-Mendelian Genetics

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%

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

• complete dominance
• incomplete dominance
• codominance
• polygenic inheritance

Homozygous is when...

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

Heterozygous is when...

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

Which of the following is a phenotype?

• Aa
• red hair
• heterozygous
• BB

What you see, or the physical appearance.

• Genotype
• Phenotype
• Homozygous
• Heterozygous

Aa, DD, bB, yy are all examples of

• phenotypes

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

This is an example of ___________?

• Incomplete dominance
• Co-Dominance

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

• Multiple alleles
• Polygenetic inheritance
• Codominance
• Incomplete Dominance
