  3. individual who has one copy of the allele for a recessive disorder and does not exhibit symptoms
  4. having a single set of chromosomes

5 True/False questions

  1. Principle of Independent AssortmentIf the genes are located on separate chromosomes, the alleles of a pair segregate independently of other allele pairs during gamete formation


  2. rule of multiplicationAdd probabilities of different combinations


  3. rule of additionProbability of combination is product of individual probabilities


  4. Principle of DominanceThe dominant allele is expressed even when only 1 gene is present; written with CAPITAL letter; Ex. PP or Pp - purple; The recessive allele is expressed only when both genes are recessive; written with lower case letter; Ex. pp- white


  5. recessive alleledescriptive of an allele in a heterozygous individual that appears to be the only one affecting a trait
