A cell that has one sets of homologous chromosomes is

• diploid

• a somatic cell

• haploid

A genotype is ______________ if it has two identical alleles for a particular gene

• heterozygous

• homozygous

Mendel's law of independent assortment

• says that organisms have two copies of every gene but donate only one during gamete formation

• is a parental cross involving only one gene

• says that characteristics are inherited independently of each other during gamete formation

• is a parental cross involving two different genes

A recessive characteristic/phenotype is

• present when the genotype has no dominant alleles

• present when the genotype has one or more dominant alleles

A genotype is ______________ if it has two different alleles for a particular gene

• homozygous

• recessive

• heterozygous

• dominant

Mendel's law of segregation

• says that characteristics are inherited independently of each other during gamete formation
