Dominant and recessive traits are concepts in genetics that describe the expression of alleles, which are alternative forms of a gene. Dominant traits mask the effects of recessive traits when present in a heterozygous genotype. The dominant allele is expressed phenotypically, overshadowing the recessive allele. In contrast, recessive traits are only expressed in the absence of a dominant allele, requiring a homozygous recessive genotype. The interaction of these alleles determines the observable characteristics (phenotype) of an organism. Understanding the dominance-recessiveness relationship is crucial in predicting and explaining the inheritance patterns of traits in offspring.
