Four-gamete test
Webobserve only three of the four possible haplotypes unless re-combination and/or parallel mutation has occurred since the originating mutations. This is the essence of Hudson’s four-gamete test (16) and allows us to identify putative boundaries of historical crossovers and gene conversion tracts (Fig. 1) to within a fraction of a read length. WebA four trait square has 256 boxes. The genotype in each box is equally likely to be produced from a cross. A two-trait Punnett Square has 16 boxes. The probability of a cross producing a genotype in any box is 1 in 16. If the same genotype is present in two boxes, its probability of occurring doubles to 1/8 (1/16 + 1/16).
