- (b)) Define Consanguineous marriages. Briefly discuss various consanguineous marriages in India with suitable illustrations. (500 words)
- Human biological variation stems from genetic and environmental interactions, shaping diverse traits across populations.
- Anthropometry uses body measurements (e.g., height, weight) to study growth, nutrition, and environmental adaptation.
- Serological markers are genetic variations in blood components (e.g., ABO blood groups, serum proteins) crucial for population genetics and migration tracking.
- Consanguineous marriages are unions between biological relatives (second cousins or closer), quantified by the coefficient of inbreeding (F).
Answer: Human biological variation is a fundamental concept in anthropology, referring to the diverse physical and genetic differences observed among human populations. This variation is shaped by a complex interplay of genetic inheritance and environmental factors. Understanding these differences is crucial for tracing human origins, migration patterns, and adaptations. Anthropometric and serological markers provide distinct yet complementary lenses through which to examine these population-level varia...
