  • Polygenic Trait
    A characteristic influenced by multiple genes, resulting in a continuous spectrum of phenotypes such as height or color intensity.
  • Dominant Allele
    A gene variant whose presence determines the phenotype, even if only one copy is present among the gene pairs.
  • Recessive Allele
    A gene variant whose effect is masked unless two copies are present, leading to its phenotype only in the absence of dominant forms.
  • Phenotype
    The observable traits or characteristics of an organism, shaped by genetic and environmental influences.
  • Pleiotropy
    A situation where a single gene influences multiple, seemingly unrelated traits, with effects varying by age or environment.
  • Incomplete Dominance
    A genetic scenario where heterozygotes display a blend of parental traits, rather than one being fully expressed.
  • Codominance
    A genetic condition where both alleles in a heterozygote are fully and simultaneously expressed, as seen in blood types.
  • Epistasis
    An interaction where one gene's effect modifies or masks the expression of another gene, leading to complex inheritance patterns.
  • Penetrance
    The proportion of individuals with a specific allele who actually display the associated phenotype.
  • Expressivity
    The degree or intensity with which a genotype is expressed in an individual, resulting in variable phenotypic outcomes.
  • Heterozygote
    An organism possessing two different alleles for a particular gene, often resulting in intermediate or unique traits.
  • Homozygote
    An organism with two identical alleles for a gene, leading to consistent expression of a specific trait.
  • Gene Interaction
    The combined influence of multiple genes on a single trait, often producing non-Mendelian inheritance patterns.
  • Dosage
    The number of dominant alleles present, which determines the intensity or degree of a trait's expression.
  • Punnett Square
    A diagrammatic tool used to predict the genetic outcomes of a cross by organizing possible allele combinations.
