Some human traits are controlled by a single gene that has more than two alleles
Some human traits are controlled by a single gene that has more than two alleles

  • Blood type is controlled by three Alleles

  • What are the major human blood types?

  • A, B, AB & O

  • Which human blood type is a universal donor?

  • Blood Type: O


Many human traits are controlled by many genes
Many human traits are controlled by many genes more than two alleles

  • Four genes control height in humans

  • Skin, eye and hair color are controlled by multiple genes


What are the female sex chromosomes
What are the Female Sex Chromosomes? more than two alleles

  • XX


What are the male sex chromosomes
What are the Male Sex Chromosomes? more than two alleles

  • XY

  • Because there is some missing genetic information in the “Y” chromosomes, Males are more likely to get a sex-linked trait
