Questions and Answers

What type of relationship between alleles is described in incomplete dominance?

  • One allele is recessive and gets completely masked by the dominant allele
  • One allele is completely dominant over the other
  • Both alleles are expressed simultaneously in distinct traits
  • Both alleles are partially expressed, resulting in an intermediate phenotype (correct)
