CISCE: Class 12

Introduction

Boys and girls develop differently even before birth. Girls usually develop a bit faster, with more similarity among themselves, while boys show more differences.

CISCE: Class 12

Sex Differences in Development

Physical Differences

Feature Girls Boys
Body fat More Less
Water in the body Less More
Muscle tissue Less More
Weight (prenatal) Less More
Teeth at the same age Mostly the same number (uniform) The number can be different

Uniformity in Development

If you compare 500 girls and 500 boys at age three:

  • Girls: Almost all will have the same number of teeth.
  • Boys: Some boys have fewer teeth, others have more (more variety).

Predictability in Growth

  • Girls usually develop at a steady, regular rate—future growth (like bone development) can be predicted more easily.
  • For boys, future growth cannot be predicted as accurately.

Emotional Development

  • All babies react strongly to loud or sudden noises.
  • As children grow, both heredity (genes) and environment (family, surroundings) shape how they develop.
  • Early experiences and feedback affect physical and emotional growth.

Real-Life Application

A dentist checking three-year-old children will find girls almost always have the same number of teeth, but for boys, the tooth count is different for many.

CISCE: Class 12

Key Point Summary

  • Girls grow in a more similar, steady pattern; boys show more differences.
  • Girls' future development is easier to predict.
  • Early experiences and the environment also affect how children develop, not just their genes.
