Explains how selective breeding methods could be used to produce a population of cats with the short legs.

Selective breeding

  • E1: bases explanation on the assumption that the mutated allele is dominant.
  • E2: breed short-legged offspring together or with mother.
  • E3: any short-legged offspring will be either heterozygous or homozygous dominant.
  • E4: to find out what they are, carry out a test cross ie breed with another normal cat (homozygous recessive).
  • E5: if no normal size legs offspring occur (after multiple breedings), then it can be taken that the tested individual is homozygous for short legs. This cat can be used for future breeding. / Any cat that produces offspring with normal legs is heterozygous and shouldn't be used for future breeding.
