An allele is:

• another word for a gene

• a homozygous genotype

• a heterozygous genotype

• one of several possible forms of a gene

Phenotype refers to the ______________________ of an individual.

• genetic makeup

• actual physical appearance

• recessive alleles

Why did Mendel choose to study pea plants in order to learn how traits are passed from parent to offspring?

• Pea plants grow quickly

• Pea plants are rare and expensive

• Pea plants are take years to grow

• Pea plants are ultraviolet

Recessive traits are ALWAYS present

• TRUE

• FALSE

Assuming that both parent plants in the diagram below are homozygous, why would all of the f1 generation have yellow phenotypes?

• because the f1 genotypes are homozygous

• because yellow is dominant over green

• because both parents passed on yellow alleles
