Question

Which one of the following techniques is employed in human genetic counselling?

• A. Serological technique
• B. Polyploidy
• C. Pedigree analysis
• D. Genetic engineering
• E. Amniocentesis

Answer 1

The correct option is C Pedigree analysis

Serology techniques serve to diagnose patients with a kind of immune deficiencies caused by lack of antibodies. Presence of multiples of complete haploid chromosomal sets is called polyploidy. Genetic engineering includes techniques for creation of recombinant DNA which carries DNA from two different sources. Use of amniotic fluid to detect presence of any genetic defect in unborn child is called as amniocentesis; the fluid has free foetal cells which are cultured and tested for any genetic disorder. Genetic counselling is to detect risk of any genetic disorder in unborn foetus; for the purpose, the pattern and inheritance of tentative disorder is studied in related individuals/ family members; it is called as pedigree analysis. Correct option is C.
