Allele : A version of a gene which encodes either the wild type gene product or a variation of the gene product. Locus : Physical position of a gene in the genome. Diploid : Possessing two copies of each gene. Normal for somatic cells (2n). Haploid : Possessing one copy of each gene. Normal gametes (n). Homozygote : A polyploid organism possessing only one allele of a gene. Heterozygote : A polyploid organism possessing multiple alleles of a gene. Hybrid : A product of genetically distinct parents. Dominant : Able to suppress the phenotype of another allele. Recessive : Phenotypically indiscernible when a dominant allele is present. Genotype : Genetic makeup of an individual....
