Genetic screening is

Result
Your answer: —  Â·  Correct: A
Explanation

The correct answer is Option 1.

Genetic screening is a specialized medical test used to identify changes in chromosomes, genes, or proteins. It primarily involves the analysis of DNA to detect the presence or absence of specific genes associated with inherited disorders or predispositions to certain diseases.

  • Why Option 1 is correct: It accurately defines the process of examining an individual's genetic material to identify specific genotypes or mutations that may lead to genetic conditions, such as Sickle Cell Anemia or Cystic Fibrosis.
  • Why other options are incorrect:
    • Option 2 refers to population genetics or genetic epidemiology rather than clinical screening.
    • Option 3 (Pedigree analysis) is a tool used to study inheritance patterns across generations but is not the screening process itself.
    • Option 4 is a narrow application; while screening can assist in infertility cases, its definition is broader and rooted in DNA analysis.
