Research draft, second pass

A second pass drafted this model: the structure a model of this thing needs, and what is known about it in the world. The line under this one says how the second half was obtained - researched against sources, or recalled without web access, in which case nothing here was read anywhere and every claim is a lead to verify. Unreviewed either way.

Purpose and description

Let an agent explain genetic recombination by type and mechanism, its role in inheritance, immunity and evolution, and its use in research and biotechnology.

The exchange or rearrangement of genetic material between DNA molecules, producing new combinations of alleles, including homologous recombination during meiosis and DNA repair, site-specific recombination, V(D)J recombination that generates antibody diversity, and gene conversion; recombination drives genetic variation and is a core tool in genetics and biotechnology.

What it is for: Genetic variation, repair and biotechnology.

It can be explain recombination mechanisms; relate recombination to inheritance and mapping; explain V(D)J recombination and immunity; describe uses in genetic engineering.

How it is recognised

Crossing over in meiosis

New allele combinations in offspring
