Multiple Choice

Let's assume in pea plants, yellow peas are dominant to green. What letter can we use to represent the allele for yellow?

• G

• g

Multiple Choice

So, Yellow (G) is dominant and Green (g) is recessive.

Remind me a again, what's a genotype?

• The genetic information, like Aa or heterozygous

• The physical parts, like being green or yellow

When you are done, get a teacher to check your answers.

Nice! Let's practice.
