What to Focus On

  • Heredity means transmission of characteristics from parents to offspring.
  • Variation means differences among individuals of the same species.
  • Variations may be acquired or inherited.
  • Chromosomes are hereditary vehicles.
  • Chromosomes are in chromatin form during interphase.
  • Higher organisms are diploid and have homologous chromosome pairs.
  • Autosomes do not determine sex.
  • Sex chromosomes determine sex.
  • Human females are XX.

Common Mistakes to Avoid

The mother decides the sex of the child because the child develops in her body.

Autosomes and sex chromosomes are the same because both are chromosomes inside the nucleus.

A gene and an allele are the same thing.
