The genotype of the short-haired parents that produced some long hair offsprings is probably heterozygous.

  • L represents short hair (dominant)
  • l represents long hair (recessive)

Therefore, if two short-haired parents produce 100 offsprings and 25 of them are long-haired, it means that they were probably heterozygous for the short hair.
