One of the pair of chromosomes that determine the sex of an individual.

Any chromosome that is not a sex chromosome.

A trait that is determined by a gene found on one of the sex chromosomes, such as the X chromosome or the Y chromosome in humans.

One of a pair of genes that tend to be inherited together.

A diagram of gene positions on a chromosome.

In chromosome mapping, an increment of 1 percent in the frequency of crossing-over.

Mutation that occurs in an organism's gametes.

Somatic-cell Mutation

A mutation that occurs in a body cell.

A gene or chromosomal mutation that influences the development of an organism cannot survive.

The loss of a part of DNA from a chromosome.

A reversal in the order of the genes, or of a chromosome segment, within a chromosome.

The movement of a segment of DNA from one chromosome to another, which results in a change in the position of the segment; also the movement of soluble nutrients from one part of a plant to another.

The failure of homologous chromosomes to separate during meiosis 1 or the failure of sister chromatids to separate during mitosis or meiosis 2.

A mutation in which only one nucleotide or nitrogenous base in a gene is changed.

A mutation in which a nucleotide or a codon in DNA is replaced with a different nucleotide.

A mutation, such as the insertion or deletion of a nucleotide in a coding sequence, that results in the misreading of the code during translation because of a change in the reading frame.

A mutation in which one or more nucleotides are added to a gene.

Linked Gene	One of a pair of genes that tend to be inherited together.
Chromosome Map	A diagram of gene positions on a chromosome.
Map Unit	In chromosome mapping, an increment of 1 percent in the frequency of crossing-over.
Germ-cell Mutation	Mutation that occurs in an organism's gametes.
Somatic-cell Mutation	A mutation that occurs in a body cell.
Lethal Mutation	A gene or chromosomal mutation that influences the development of an organism cannot survive.
Deletion	The loss of a part of DNA from a chromosome.
Inversion	A reversal in the order of the genes, or of a chromosome segment, within a chromosome.
Translocation	The movement of a segment of DNA from one chromosome to another, which results in a change in the position of the segment; also the movement of soluble nutrients from one part of a plant to another.
Nondisjunction	The failure of homologous chromosomes to separate during meiosis 1 or the failure of sister chromatids to separate during mitosis or meiosis 2.
