  • What do the leters on the outside of punnett square stand for?
    The parents' genotype
  • What is an allele?
    one member of a pair of genes occupying a specific spot on a chromosome that controls the same trait

  • Who is the father of gentics?
    Gregor Mendel
  • What is a gene?
    segment of DNA that is transferred from a parent to offspring and determines some characteristic of the offspring.
