HB Genetics Review 2023

What do we call the result of the genotype (for example, the color of the peas)?

• Visible traits
• Physiotrait
• Genotype 2
• Phenotype

If green is dominant over purple, then what is the genotype for this individual?

• Purple
• Green
• GG
• gg

Tt is-

• homozygous dominant
• homozygous recessive
• heterozygous
• none of these

this image is an example of

• codominance
• dominance
• incomplete dominance

A breed of chicken shows codominance for feather color. One allele codes for black feathers, another codes for white feathers. The feathers of heterozygous chickens of this breed will be:

• all black
• all white
• all gray
• speckled black and white

Based off this punnett square, what fraction of the offspring will have wrinkled, yellow seeds?

• 9/16
• 3/16
• 1/16
• 16/16

What goes in box 3

• Aabb

• AABB

• AAbb

• aaBb

A white mouse with red eyes is crossed with a black mouse with brown eyes. The white mouse is recessive for both of its traits. The black mouse is dominant for both of its traits.

This cross would be

• BBEE x bbee

• BBEe x BbEe

• BbEE x BbEe

• BBee x BBEE

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%

What types of blood can a person with AB RECEIVE?

• B only
• AB, A, B, O
• AB and O only
• A only
