Multiple      Alleles

By: Nathan Swan

  • Different alleles in a gene slightly change the DNA strand
  • There are often hundreds of alleles for a single gene
  • All alleles fall on an allelic series, from no activity to very high activity
  • The more active an allele is, the higher the chance of containing it
  • Heterozygotes usually have a phenotype between full dominance and blending inheritance

Schizophrenia
