Method Primary source [19] abstract: "[Investigators] have developed a system that utilizes human DNA-derived yeast artificial chromosomes (YACs) as marker chromosomes to study factors that contribute to the fidelity of meiotic chromosome transmission. Since aneuploidy for the YACs does not affect spore viability, different classes of meiotic missegregation can be scored accurately in four-viable-spore tetrads including precocious sister separation, meiosis I nondisjunction, meiotic chromatid loss, and meiosis II nondisjunction."
Comments P.475 right column bottom paragraph:"Given the profound adverse effects of aneuploidy on human health, it is not surprising that cells with an unbalanced karyotype are rare. In budding and fission yeast, for example, the chromosome loss rate is estimated to be between 1 × 10^−5 and 1 × 10^−4 per generation [primary sources] (Table 1)."
