Question

Incomplete genetic linkage is far more common than complete linkage. What is the term for gametes produced when recombination shuffles the alleles of linked genes?

Answer 1

Explanation:

Genetic recombination is the process by which a strand of genetic material (usually DNA, but can also be RNA) is cut and then attached to a molecule of different genetic material. In eukaryotes, recombination commonly occurs during the meiosis of sexual reproduction3 (the process by which eukaryotes generate gametes), such as chromosomal cross-linking between paired chromosomes. This process leads to the progeny having combinations of genes different from those of their parents and can produce chimeric alleles. In evolutionary biology it is believed that this mixture of genes has several advantages, including that it allows organisms to reproduce sexually and avoid Muller's ratchet. In vertebrates there is also a type of special genetic recombination in B and T cells of the immune system, called recombination V (D) J, which is responsible for generating the tremendous variability of antibodies and T-cell receptors necessary for the response immune. Site-specific recombination is a special type of homologous recombination that occurs in specific, short and homologous regions, existing in both fragments to recombine. It is usually typical of viruses, which use it to integrate into the host genome.
