Top of Form

                     Autosome: Any chromosome other than the sex chromosome.

                     Agglutination: Generally refers to the clumping of red blood cells.

                     Carrier: A heterozygous individual who is phenotypically normal but carries a recessive gene, which can be transmitted to his offspring.

                     Dominant: Phenotypic expression of a gene in both homozygous and heterozygous conditions.

                     Homozygous: Having identical alleles. For example, (TT or tt) at the corresponding gene loci on homologous chromosomes.

                     Heterozygous: Having two different alleles. For example, (T, t) at the corresponding gene loci on homologous chromosomes.

                     Heterogamesis: The process by which two dissimilar gametes are produced from one of the two sexes.

                     Linkage: The tendency of two or more genes to remain together on the same chromosome during the course of inheritance.

                     Sex Chromosomes: Chromosomes that determine the sex of an individual.

                     Recessive: Incapable of phenotypic expression unless both the members of a pair of homologous chromosomes carry the responsible allele.
