Allele one of two or more alternative forms of a gene that arise by mutation and are found at the same place on a chromosome.
Genotype the genetic constitution of an individual organism.
Phenotype the set of observable characteristics of an individual resulting from the interaction of its genotype with the environment.
Codominance a relationship between two versions of a gene. Individuals receive one version of a gene, called an allele, from each parent. If the alleles are different the dominant one will be expressed, while the other one is masked
Incomplete Dominance refers to a genetic situation in which one allele does not completely dominate another allele, and therefore results in a new phenotype.
Law of Independent assortment the principle, originated by Gregor Mendel, stating that when two or more characteristics are inherited, individual hereditary factors assort independently during gamete production, giving different traits an equal opportunity of occurring together.
Law of Segregation the principle, originated by Gregor Mendel, stating that during the production of gametes the two copies of each hereditary factor segregate so that offspring acquire one factor from each parent.
