    punnett square
  • a cell containing only one set of chromosomes - gametes
    haploid
  • Genotypic probability of having Aa offspring from crossing AA x Aa

  • An allele that is masked when a dominant allele is present
    recessive allele
  • The physical traits that appear in an individual as a result of its genotype
    phenotype
  • when traits are determined by alleles on the sex chromosomes
    sex-linked
  • Having two identical alleles for a trait
    homozygous
  • An allele whose trait always shows up in the organisms when the allele is present
    Dominant allele
  • Genotypic probability of having aa offspring from crossing aa x AA
