  • Monohybrid Cross
    Mating between two organisms to analyze inheritance patterns of alleles at a single gene locus.
  • Allele
    A variant form of a gene, represented by different letters or symbols, inherited from each parent.
  • Punnett Square
    A grid tool used to predict possible genotypes and phenotypes of offspring from parental alleles.
  • Genotype
    The genetic makeup of an organism, described by the combination of alleles it possesses.
  • Phenotype
    The observable trait or characteristic resulting from the interaction of an organism's genotype and environment.
  • Dominant
    An allele that masks the effect of another allele and determines the phenotype when present.
  • Recessive
    An allele whose effect is masked by a dominant allele and only expressed when two copies are present.
  • Heterozygous
    A genotype consisting of two different alleles for a specific gene, one dominant and one recessive.
  • Homozygous
    A genotype with two identical alleles for a gene, either both dominant or both recessive.
  • Gamete
    A reproductive cell carrying a single allele for each gene, combining during fertilization to form offspring.
  • Wild Type
    The most common allele or phenotype found in a natural population, often denoted with a plus sign.
  • Mutant
    A variant allele or phenotype differing from the wild type, often resulting in a distinct trait.
  • Offspring
    The resulting individuals produced from the mating of two parent organisms in a genetic cross.
