Science / Biology / Alleles: Alternate forms of a gene.

Crossing Over

Science / Genetics / Crossing Over: The breaking during meiosis of one maternal and one paternal chromosome, the exchange of corresponding sections of dna, and the rejoining of the chromosomes. This process can result in an exchange of MORE

Gene Product

Science / Genetics / Gene Product: The biochemical material, either rna or protein, resulting from expression of a gene. The amount of gene product is used to measure how active a gene is: abnormal amounts can be correlated with diseas MORE


Science / Genetics / Heterozygosity: The presence of different alleles at one or more loci on homologous chromosomes. MORE


Science / Genetics / Fingerprinting: In genetics, the identification of multiple specific alleles on a person's dna to produce a unique identifier for that person. MORE

Genetic Illness

Science / Genetics / Genetic Illness: Sickness, physical disability, or other disorder resulting from the inheritance of one or more deleterious alleles. MORE


Science / Genetics / Heterozygote: Having two alleles that are different for a given gene. MORE
