State that two identical homozygous individuals that breed together will be pure-breeding
Answered
Two identical homozygous individuals that breed together are referred to as pure-breeding. This means that they possess two identical alleles for a particular trait, and when they mate, all offspring will inherit the same alleles from both parents. As a result, the offspring will consistently express the same phenotype for that trait across generations.
Key Points:
- Homozygous Individuals: These individuals have two identical alleles for a specific gene (e.g., AA or aa).
- Pure-Breeding: When two homozygous individuals (AA × AA or aa × aa) breed, they produce offspring that are also homozygous for that trait (all AA or all aa), leading to uniformity in the expression of that trait.
- Consistent Traits: Pure-breeding individuals will produce offspring with predictable and consistent traits, making them valuable in breeding programs and genetic studies.
