Genome

Peptide

Biology; Genome

Two or more amino acids joined by a bond called a "peptide bond." See also: polypeptide.

The probability of a gene or genetic trait being expressed. "Complete" penetrance means the gene or genes for a trait are expressed in all the population who have the genes. "Incomplete" penetrance ...

Shotgun method

Biology; Genome

Sequencing method that involves randomly sequenced cloned pieces of the genome, with no foreknowledge of where the piece originally came from. This can be contrasted with "directed" strategies, in ...

Meiosis

Biology; Genome

The process of two consecutive cell divisions in the diploid progenitors of sex cells. Meiosis results in four rather than two daughter cells, each with a haploid set of chromosomes. See also: ...

Coisogenic or congenic

Biology; Genome

Nearly identical strains of an organism; they vary at only a single locus..

Single nucleotide polymorphism (SNP)

Biology; Genome

DNA sequence variations that occur when a single nucleotide (A, T, C, or G) in the genome sequence is altered. See also: mutation, polymorphism, single-gene disorder.

Mendelian inheritance

Biology; Genome

One method in which genetic traits are passed from parents to offspring. Named for Gregor Mendel, who first studied and recognised the existence of genes and this method of inheritance. See also: ...
