Monohybrid Cross
The procedure that shows how the offspring will come out.
Alleles
One of the alternative forms of a single gene. In pea plants, a single gene codes for seed color, and it comes in two alleles--one codes for yellow seeds, the other for green seeds.
Homologous Chromosomes
Chromosomes that are the same in size and function. Species that are diploid (have two sets of chromosomes) have matching pairs of homologous chromosomes; one member of each homologous pair is inherited from the male, the second member of each homologous pair is inherited from the female.
Dominant Allele
An allele that is expressed in the heterozygous condition
Recessive Allele
An allele that is not expressed in the heterozygous condition.
Homozygous Dominant

Homozygous Recessive

Diploid
Possessing two sets of chromosomes. All human cells are diploid with the exception of human gametes (eggs and sperm), which are haploid. Such haploid cells possess only a single set of chromosomes.
Haploid
Possessing a single set of chromosomes. Human gametes (eggs and sperm) are haploid cells, because they have only a single set of chromosomes. All other cells in the human body are diploid, meaning they possess two sets of chromosomes.
Homologous Chromosomes

Genes
null
Sex Chromosomes
The chromosomes that determine the sex of an organism. The X or Y chromosomes in humans.
Non-Disjunction
The failure of homologous or sister chromatids to separate during meiosis, resulting in unequal numbers of chromosomes in the daughter cells. Nondisjunction results in aneuploidy.
