Industry:Biotechnology
The formation of nodules by symbiotic bacteria on the roots of plants.
Industry:Biotechnology
The fraction of a cell population that takes up foreign DNA; expressed as the number of transformed cells divided by the total number of cells in a population.
Industry:Biotechnology
The frequencies of genotypes at a locus resulting from random mating at that locus; for two alleles, <i>A</i><sub>1</sub> and <i>A</i><sub>2</sub>, with respective frequencies <i>p</i> and <i>q</i>, the Hardy-Weinberg equilibrium frequencies are <i>p</i><sup>2</sup> <i>A</i><sub>1</sub><i>A</i><sub>1</sub>, 2<i>pq</i> <i>A</i><sub>1</sub><i>A</i><sub>2</sub>, <i>q</i><sup>2</sup> <i>A</i><sub>2</sub><i>A</i><sub>2</sub>. Despite the simplifying assumptions required to predict these frequencies, most loci in most populations are in Hardy-Weinberg equilibrium. Thus the Hardy-Weinberg law, which predicts these frequencies, is one of the great unifying themes of biology.

Industry:Biotechnology
The fusion of reproductive cells from closely related parents, i.e., inbreeding. <i>cf</i> exogamy.
Industry:Biotechnology
The fusion of reproductive cells from distantly related or unrelated organisms, i.e., outbreeding. <i>cf</i> endogamy.
