Allele
One member of a pair (or any of the series) of genes occupying a specific spot on a chromosome (called locus) that controls the same trait
1 of 12
Locus
mathematics) The set of all points whose coordinates satisfy a given equation or condition.
2 of 12
Phenotype
The physical appearance or biochemical characteristic of an organism as a result of the interaction of its genotype and the environment.
3 of 12
Genotype
A set of alleles that determines the expression of a particular characteristic or trait (phenotype).
4 of 12
Dominant
An allele or a gene that is expressed in an organism’s phenotype, masking the effect of the recessive allele or gene when present
5 of 12
Recessive
Of, or pertaining to, a gene (or allele) whose phenotypic expression is masked by a dominant gene (or allele). Both alleles of the recessive form must be present for this to be expressed.
6 of 12
Apoptosis
Programmed cell death as signalled by the nuclei in normally functioning human and animal cells when age or state of cell health and condition dictates.
7 of 12
Homologus
Homologous chromosomes are chromosome pairs, one from each parent, that are similar in length, gene position, and centromere location. The position of the genes on each homologous chromosome is the same, however the genes may contain different allele
8 of 12
Chromosones
Definition: A chromosome is a long, stringy aggregate of genes that carries heredity information (DNA) and is formed from condensed chromatin. A non-duplicated chromosome is single-stranded and is comprised of a centromere region that connects two ar
9 of 12
Sister Chromatids
Sister chromatids are two identical copies of a single chromosome that are connected by a centromere.
10 of 12
Haploid
A haploid cell is a cell that contains one complete set of chromosomes. Gametes are haploid cells that are produced by meiosis.
11 of 12
Diploid
A diploid cell is a cell that contains two sets of chromosomes. One set of chromosomes is donated from each parent.
