How many additional parameters in a conversion model can be evaluated using "corresponding-site" events?

Abstract

Contrary to a recent claim by B.C. Lamb and S.A. Zwolinski (1992), the frequencies of "corresponding-site" conversion events (all four chromatids involved in conversion at the same locus in the same meiotic cell) can be used to evaluate only two parameters not otherwise calculable: a coincidence parameter and the frequency of conversion-type events in which a normal 1:1 ratio is restored.Key words: Ascobolus immersus, gene conversion.
