Genetics

The alleles of a particular gene are different.

• homozygous

• heterozygous

• genotype

• phenotype

The two alleles for a trait separate when gametes are formed.

• law of segregation

• law of separation

• law of independent assortment

• law of codominance

The alleles of different genes separate independently of one another during gamete formation.

• law of segregation

• law of separation

• law of independent assortment

• law of codominance

Not expressed when the dominant form of the trait is present.

• recessive
