Homologous Chromosomes
A process in cell division during which the number of chromosomes decrease to half the original by two division of the nucleus which results in the production of sex cells.
Melosis
One of the pair of chromosomes that determine the sex of an individual.
Sex Chromosomes
A diagram that shows the occurrence of a genetic trait in several generations of a family.
Pedigree
A molecule that is present in all living cells and that contains the information that determines the traits that a living thing inherits and needs to live.
DNA
In a nucleic-acid chain, a sub unit that consists of a sugar, a phosphate, and a nitrogenous base.
Nucleotide
