Homozygous

• the passage of genetic information from a parent or parents to offspring

• having two alleles that are the same

• having two alleles that are different

• a segment of DNA that determines or helps to determine a trait

Answer explanation

Homozygous means having two alleles that are the same. It is a genetic condition where an individual inherits identical alleles for a particular trait.
