Industry:Natural environment
A set of closely linked genes that tends to be inherited together as a unit; a particular set of alleles at linked loci that are found together on a single homolog; a genetic type; a unique DNA sequence.

A technique for separating different types of molecules based on their patterns of movement in an electrical field.
Industry:Natural environment
An aquatic vertebrate whose embryonic stage is not surrounded by an amnion. Fishes and amphibians are anamniotes.
Industry:Natural environment
Any change in chromosome structure or number. Although chromosomal abberations can be mechanisms for enhancing genetic diversity, such alterations are usually deleterious or ill-adaptive; includes deficiency, duplication, inversion, translocation, aneuploidy, polyploidy, or any other change from the normal pattern.
Industry:Natural environment
The asexual production of diploid offspring without the fusion of gametes. The embryo develops by mitotic division of the maternal or paternal gamete, or in the case of plants, by mitotic division of a diploid cell of the ovule.
Industry:Natural environment
May be conveniently summarized as: encrusting (lichen-like); branched (staghorn-like); massive (rock-like); sub-massive (pillar-like); tabulate (table-like); foliose (scroll-like); and solitary.
