a)

Tt

b)

tt

c)

TT

d)

T

3.

What does heterozygous mean?

a)

An organism that has the same alleles for a trait (TT or tt)

b)

An organism that has different alleles for a trait (Tt)

c)

When neither allele is fully dominant; offspring is a mixture of both

d)

the different forms of a trait (hair color--> brown, blonde, red

4.

Law which states that different traits are inherited independently of each other

a)

Law of independent assortment

b)

Genetics law

5.

Law states that 1 allele is more dominant than the other. Recessive allele is only expressed when dominant is not present

a)

Law of dominance

b)

Law of inheritance

6.

If your genotype is Bb, then you can only pass a B or b to your child but you can't pass both.

a)

Law of Dominance

b)

Law of Segregation

c)

Law of Independent Assortment

7.

An organism is a hybrid genotype (Tt) but is appears tall instead of short.

a)

Law of Dominance

b)

Law of Segregation

a)
AA
b)
Aa
c)
aa
d)
none of these
9.

Law of Independent Assortment

a)

The way an organism looks and behaves

b)

Genes for different traits are inherited independently of each other

c)

Alleles for a trait are the same

10.

Genotype

a)

Different forms of a gene

b)

Alleles for a trait are the same

c)

The allele combination of an organism

11.

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.

12.

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.
