Multiple Choice

Gregor Mendel studied ______ and was able to determine some "rules" for how traits where passed from one generation to the next.

• carrots

• oats

• peas

• beans

Multiple Choice

What is another, more scientific name for the Parent Generation (the one you start with)?

• P1

• Purebred generation

• Ancestors

Multiple Choice

When two purebred parents with two different traits are "mated", what is the result?

• All of the offspring have 1 of the traits

• The offspring have a mix or blend of the two traits

• Some of the offspring have one trait, the rest of the offspring have the other

Multiple Choice

What trait do the F1 generation all show (phenotype)?

2 alleles --> 1 from each parent

a trait can be hidden by another

2 alleles are separated

1 trait does not affect another

• 2 alleles --> 1 from each parent

• a trait can be hidden by another

• 2 alleles are separated

• 1 trait does not affect another

How do I feel about what we learned today about Mendel's experiment, laws, and genetics?

• Great! It all makes sense

• Okay but I could use some practice

• Terrible, this all makes no sense
