Making chromosomes hot for breakage
Meiosis is a special cell division program that reduces the diploid chromosome set to a haploid set for sexual reproduction. Reductional segregation of homologous chromosomes is helped by physical linkages (crossovers) provided by recombina-tion. A long-standing problem in biology has been to understand how meiotic recom-bination is controlled, since its initiation by DNA double-strand breaks (...
متن کاملPhyletic hot spots for B chromosomes in angiosperms.
We determined whether supernumerary B chromosomes were nonrandomly distributed among major angiosperm lineages and among lineages within families, as well as the identity of lineages with unusually high B-chromosome frequencies (hot spots). The incidence of B chromosomes for each taxon was gathered from databases showing species with and without these chromosomes (among species with known chrom...
