A(n) ____________________ is a different form of a _________ passed from generation to generation.

• gene, allele

• inheritance, gene

• allele, gene

• gene, DNA

The ___________________ trait will show in the phenotype if it is present and is characterized by a capital letter.

• Homozygous

• Heterozygous

• Dominant

• Recessive

The ___________________ trait is typically hidden unless the individual is homozygous for this trait. This trait is characterized by a lower case letter.

• Homozygous

• Heterozygous

• Dominant

• Recessive

An organism is _________________________ if both alleles for a trait are the same.

• Homozygous

• Heterozygous

• Dominant

• Recessive

An organism is ____________________________ if the alleles for a trait are different.

• Homozygous

• Heterozygous

• Dominant

• Recessive

An organism’s allele pairs are called its _________________________. This refers to the genetic make-up of the offspring.

• Homozygous

• Dominant

• Genotype

• Phenotype

The expression of an allele pair, or the way an organism looks or behaves, is called its __________________________. It is usually what you can physically see.

• Homozygous

• Dominant

• Genotype

• Phenotype

Mendel’s law of segregation states that the two alleles for each trait separate from each other during meiosis and then unite during fertilization.
