Inheritance & Mendel Formative Assessment

The word used to describe individual with the same dominant or recessive allele.

Example: AA or aa

• homozygous

• heterozygous

• genotype

• phenotype

The word used to describe individual with one dominant and one recessive version of an allele.

Example: Aa

• homozygous

• heterozygous

• genotype

• phenotype
