Abstract
A centromere map is derived from XXX and XXY trisomies of maternal origin. Preliminary data suggest reduced recombination in the tetrads giving rise to mei I nondisjunction, but an excess of recombination in the pericentric region. As in Drosophila, multichiasmate tetrads may be more at risk of nondisjunction than nullochiasmate tetrads.Keywords
