Think about all the "Genetic- Type" questions you've ever had. What are 1 or 2 things you would like to know about by the end of this unit? I will try to make sure we talk about them!

This is review!

Multiple Choice

A student is constructing a model of a single chromosome. The individual segments within the chromosome represent genes that control certain traits.

Based on the model, which term BEST describes gene pair #1.

• Dominant

• Recessive

• Homozygous

• Heterozygous

Multiple Select

Which is a homozygous genotype(s)? select all that apply.

• BB

• bb

• Bb

• B

Multiple Choice

What offspring ratio will you get from crossing a homozygous dominant man (BB) for eye color with a homozygous recessive (bb) woman?

Hint: draw a Punnett Square

• 50% BB; 50%bb

• 25%bb; 75%Bb

• 100%BB

• 100%Bb
