Gene Conversion - Effect

Effect

Normally, an organism that has inherited different copies of a gene from each of its parents is called heterozygous. This is generically represented as genotype: Aa (i.e. one copy of variant (allele) 'A', and one copy of allele 'a'). When a heterozygote creates gametes by meiosis, the alleles normally split, and end up in a 1:1 ratio in the resulting cells. However, in gene conversion, a ratio other than the expected 1A:1a is observed, in which A and a are the two alleles. Such examples are 3A:1a, 1A:3a, 5A:3a or 3A:5a. In other words there can, for example, be three times as many A alleles as a alleles expressed in the daughter cells, as is the case in 3A:1a.

Famous quotes containing the word effect:

    The law before us, my lords, seems to be the effect of that practice of which it is intended likewise to be the cause, and to be dictated by the liquor of which it so effectually promotes the use; for surely it never before was conceived by any man entrusted with the administration of public affairs, to raise taxes by the destruction of the people.
    Philip Dormer Stanhope, 4th Earl Chesterfield (1694–1773)

    Governing today means giving acceptable signs of credibility. It is like advertising and it is the same effect that is achieved—commitment to a scenario.
    Jean Baudrillard (b. 1929)

    Before the effect one believes in different causes than one does after the effect.
    Friedrich Nietzsche (1844–1900)
