Revision summary
Anthropometry is standardised body measurement. Nutrition uses height, weight, arm circumference, and z-scores. Stunting and wasting separate chronic from acute lack. Sport uses somatotype and proportions as one input beside physiology. Boas’s plasticity warning still forbids racial misuse.
Model answer
Copper italics in this answer — like this — are the key facts. Each one is unpacked in the Facts & figures rail.
Introduction
Anthropometry is the standardised measurement of the human body. It is a cheap, repeatable tool for nutrition and for the morphology of sport, not a return to racial typing.
Body
Method
- Height, weight, sitting height, circumferences, and skinfolds follow Martin landmarks and Tanner growth logic.
- Indices include BMI, waist–hip ratio, and mid-upper-arm circumference. In children, z-scores against WHO or ICMR references flag stunting and wasting.
- Boas already used anthropometry to show plasticity. That is the opposite of a fixed race chart.
Nutritional status
- Stunting (low height-for-age) records chronic lack. Wasting (low weight-for-height) records acute lack. Underweight mixes both.
- Skinfolds and arm muscle area estimate fat and protein stores. High BMI can hide micronutrient lack.
- Community surveys in India still rely on these measures because they travel to the village.
Sports capability
- Somatotypes after Sheldon, later Heath–Carter, sort endomorphy, mesomorphy, and ectomorphy. Sprinters and weightlifters cluster differently from distance runners.
- Limb length, sitting-height ratio, and grip or reach help selection. They do not replace VO2 max, skill, or training.
- Population means, as in some Inuit or high-altitude chests, are starting points, not destiny. Nutrition in childhood writes the adult athlete as much as a gene.
Ethic
- Use anthropometry for health and performance. Do not revive it as a ladder of peoples.

Conclusion
Anthropometry assesses growth, undernutrition, and sport build through standardised sizes. It is a bio-cultural instrument when references and training are named, not a race science.

Is a mesomorph automatically a better athlete?
Shape helps some events. Skill, training, and oxygen transport decide performance.
-
Can BMI diagnose an individual?
It screens. Muscle, age, and oedema can mislead. Combine with other measures.

In what manner is our understanding of serogenetics and cytogenetics useful in reproductive biology? What are the major ethical issues involved in reproductive technology?
Applications of Anthropology
Serogenetics uses blood groups and serum protein markers for paternity disputes, Rh incompatibility, and fertility-related polymorphism. Cytogenetics uses karyotyping to detect numerical and structural chromosomal defects behind miscarriage and congenital disorders. IVF, ICSI and PGD extend these tools into clinical reproduction. Ethical flashpoints include commercial surrogacy, commodification of reproduction, eugenic selection through PGD, and unclear parentage when donors are involved. India's ART and Surrogacy Acts, 2021, aim to regulate practice while protecting dignity.

Examine the utility of human remains in forensic analysis. Discuss the facial reconstruction technique
Applications of Anthropology
Forensic anthropology estimates sex, age, stature and trauma from bones and teeth, and it records context. Krogman and Stewart standardised osteological identification. DNA STRs and dentistry confirm identity when references exist. Clyde Snow’s human-rights cases show remains as testimony. Facial reconstruction uses tissue-depth markers, as in Gerasimov and Gatliff, now often with CT and 3D prints. The face is an approximation to prompt recognition, not a certain portrait. Ethics include family consent and no racial or caste over-claim.

What are genetic markers? Discuss their applications in understanding population variation, disease association and forensics
Applications of Anthropology
A genetic marker is a heritable polymorphism that can be read in families or populations. Classical markers include ABO and proteins. DNA markers include SNPs, STRs, mtDNA and Y haplotypes. Population applications map variation and movement and undermine typological race. Disease applications include sickle-cell and malaria, HLA, counselling, and GWAS. Forensic applications include STR identification, mtDNA from degraded samples, and Y-lineage in mixtures. Lewontin’s within-group diversity and Jeffreys’s DNA fingerprinting are central names.
