Description

  • Heredity and variation: Mendelian inheritance;
  • deviations from Mendelism - incomplete dominance, co-dominance, multiple alleles and inheritance of blood groups, pleiotropy;
  • elementary idea of polygenic inheritance; chromosome theory of inheritance;
  • chromosomes and genes;
  • Sex determination - in humans, birds and honey bee;
  • linkage and crossing over;
  • sex linked inheritance - haemophilia, colour blindness;
  • Mendelian disorders in humans - thalassemia; chromosomal disordersin humans;
  • Down's syndrome, Turner's and Klinefelter's syndromes.
