Answer
Genetic screening typically involves testing individuals to determine if they carry a specific allele, particularly those that may result in genetic disorders. This proactive approach allows for early diagnosis and informed decision-making regarding health and reproduction.
Step 2
B. preventing individuals with particular alleles from breeding.

Answer
While this involves genetic management, it does not constitute genetic screening. Preventing breeding based on alleles is more aligned with genetic intervention rather than the screening process itself.
Step 3
C. removing a mutated allele from a chromosome.

Answer
This describes a potential therapeutic approach rather than screening. Genetic screening focuses on the identification of alleles, not their active removal.
Step 4
D. curing an individual of an inherited disease.

Answer
Curing an inherited disease is a medical intervention that might result from information obtained through screening, but it does not itself define genetic screening.
