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

linkage and crossing over

Linkage Genes that are physically located on the same chromosome are said to be “linked”. Linked genes are said to be “mapped” to the same chromosome. - ppt download
