Multiple Crossovers can involve more than two chromatids - Study

Tetrad analysis can also show two other important features of crossing-over. First, in one meiocyte several crossovers can occur along a chromosome pair. Second, in any one meiocyte these multiple crossovers can involve more than two chromatids. To think about this issue, we need to look at the simplest case: double crossovers. To study double crossovers, we need three linked genes.For example,in a cross such as ABC      x       abc many different tetrad types are possible, but some types are useful in the present connection because they can be accounted for only by double crossovers involving more
