d)

All of these

4.

Why were pea plants perfect a study on Heredity?

a)

Pea plants are complex

b)

They were easy to study

c)

One gene controlled one trait. (i.e. it was simple)

d)

One gene was controlled by multiple traits

5.

Mendel's Law of Segregation means?

a)

Every person has two alleles for each trait, they segregate from each other and the dominant is passed more often.

b)

Every person has two alleles for each trait, Where two traits are being passed, they do not effect each other.

c)

Every person has two alleles for each trait, they segregate from each other and are passed down at random.

d)

Every person has two alleles for each trait, they segregate from each other and the recessive is passed more often.

6.

What is Mendel's Law of Independent Assortment?

a)

If the recessive allele is passed for one trait, then it is more likely that the recessive allele will be passed for the other trait.

b)

The passing of allele of one trait does not affect the passing of allele of another trait.

c)

If the dominant allele is passed for one trait, then it is more likely that the dominant allele will be passed for the other trait.

d)

If the dominant allele is passed for one trait, then it is more likely that the recessive allele will be passed for the other trait.
