Review: Codominance, incomplete, blood types pedigree

____________ occurs when the dominant and recessive traits are blended in the heterozygous genotype.

• Codominance

• Punnett squares

• Complete dominance

• Incomplete dominance

Which of the following refers to a complete dominant cross?

• One allele completely dominates over the other.

• The two alleles are equally seen in the heterozygous genotype.

• The two alleles are blended in the heterozygous genotype.

• Neither allele is seen in the phenotypes.

In the image above, the trait for flower color is controlled by codominance. R codes for red flowers and W codes for white flowers. Which of the following correctly reports the phenotypes?

• 100% red flowers

• 50% white flowers and 50% pink flowers

• 50% red flowers and 50% red and white flowers

• 50% white flowers and 50% red flowers

This is an example of ___________?

• Incomplete dominance
• Co-Dominance

A red flowered plant (RR) is crossed 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%

What type of inheritance do two alleles have if their traits blend together?

• Incomplete Dominance

• Co-Dominance

• Mendelian Inheritance (Complete Dominance)

• Homozygous Inheritance

This is an example of ___________.

•  Incomplete Dominance
•  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

This is an example of ___________.

• Incomplete Dominance
• Codominance

If two parents are heterozygous for type A blood, what is the probability that their offspring would have type O blood?

• 100 %
• 75%
• 50%
• 25%
