If two alleles are the same for a certain trait they are considered

• Homozygous

• Twins

• Heterozygous

• Common

Physical traits that are expressed are known as ____________

Sections of DNA that have instructions for a specific trait are called _______________

• Blueprints

• Genes

• Heterozygous

• Fragments

Chromosomes are
