“One hundred randomly selected metaphase cells were scored for the presence of chromatid gaps and breaks.”

“One is the nonreciprocal transfer of information of both DNA strands of a donor chromatid to a chromatid of the homologous chromosome.”

“On average, each double-crossover bivalent produces one double-crossover chromosome in the absence of chromatid interference.”

“The rate at which heterozygosity is lost depends on the extent to which chromosomes and chromatids segregate randomly during anaphase.”

“Early in meiosis, each pair of homologs comes together to form a tetrad containing two pairs of sister chromatids.”

“Double reduction is a phenomenon that two sister chromatids of a chromosome sort into the same gamete.”
