1.

__________________: Allele pairs separate during gamete formation, so each gamete carries only one allele for each gene.

a)

Law of Independent Assortment

b)

Polygenic Alleles

c)

Law of Segregation

2.

___________________: Each allele pair segregates randomly to the haploid gametes in meiosis, so which allele a gamete receives for one gene is not affected by which allele the gamete receives for another gene.

a)

Sex-linked Genes

b)

Law of Segregation

c)

Law of Independent Assortment

3.

__________________: A form of inheritance where neither allele is dominant, resulting in a phenotype that is an intermediate between the two homozygous phenotypes

a)

Sex-linked Genes

b)

Codominance

c)

Incomplete Dominance

4.

__________________: Genes found on sex chromosomes. In class, we discussed that some of these genes are only on the X chromosome.

a)

Sex-linked Genes

b)

Codominance

c)

Incomplete Dominance

5.

_________________: A form of inheritance where both alleles are separately and equally expressed in a heterozygous individual.

a)

Codominance

Sex-linked Genes

6.

___________________: A form of inheritance that occurs when one characteristic is controlled by more than one gene.

a)

Allele
