Study Notes
Definitions of Terms Related to Genetics
- Purebred: Offspring resulting from many generations of organisms that consistently exhibit the same traits.
- Hybrid: An organism possessing two different alleles for a specific trait, classified as heterozygous.
- Dominant Allele: An allele whose associated trait is always expressed in the organism in the presence of at least one dominant allele.
- Recessive Allele: An allele whose associated trait is hidden or not expressed when a dominant allele is present.
- Codominance: A genetic scenario where both alleles contribute to the phenotype, allowing both traits to be visibly expressed.
- Incomplete Dominance: A genetic condition where the phenotype of offspring reflects a blend of the parental traits.
- Phenotype: The observable physical expression or characteristics of an organism, influenced by its genotype.
- Genotype: The genetic constitution or specific allele combinations of an organism.
- Homozygous: The condition of having two identical alleles for a particular trait, which can be either dominant or recessive.
