  1. Class Notes 6: Complex Inheritance

  2. I. Incomplete Dominance • When neither trait is dominant. • Result is a blend of both traits. • Ex: white (rr) x red(RR) = pink (Rr)

  3. II. Codominance • When both traits are dominant • Result is that both traits show Ex: brown x white = brown spotted

  4. III. Multiple Alleles • When there are more than two alleles of each trait • Ex: Rabbit fur color has four alleles for one trait

  5. IV. Polygenic Traits • When more than one gene is in charge, so inheritance rules are very complex. • Ex: Eye color and skin color

  6. V. Sex-linked trait • When a gene for a trait is located on the X or Y chromosome. Ex: Colorblindness is on the X chromosome. *Why are males more likely to be colorblind?
