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:
“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)
“That when that knot’s untied that made us one,
I may seem thine, who in effect am none.
And if I see not half my dayes that’s due,
What nature would, God grant to yours and you;”
—Anne Bradstreet (c. 1612–1672)
“At the heart of the educational process lies the child. No advances in policy, no acquisition of new equipment have their desired effect unless they are in harmony with the child, unless they are fundamentally acceptable to him.”
—Central Advisory Council for Education. Children and Their Primary Schools (Plowden Report)
