DDK和C57 BL/6近交系小鼠的F1回交在两条不同染色体11和X上的位点上显示出传递比畸变。X染色体上的传递率畸变仅限于雌性后代,而11号染色体上的传递率畸变存在于两性后代中。在这篇文章中,我们调查是否在一条染色体上的基因座的等位基因的遗传是独立的等位基因的遗传。在雄性后代中发现两条染色体上等位基因的遗传之间存在很强的非随机关联,而在雌性后代中发生独立分配。我们还提供了证据表明,这种现象发生的机制涉及优先共分离的非双亲染色单体的两条染色体在第二次减数分裂分裂,卵子受精后,C57 BL/6精子携带Y染色体。这些观察结果证实了精子在雌性减数分裂过程中对染色单体分离的影响,并表明Y染色体上的一个或多个位点参与了减数分裂驱动的这种情况。
F1backcrosses involving the DDK and C57BL/6 inbred mouse strains show transmission ratio distortion at loci on two different chromosomes, 11 and X. Transmission ratio distortion on chromosome X is restricted to female offspring while that on chromosome 11 is present in offspring of both sexes. In this article we investigate whether the inheritance of alleles at loci on one chromosome is independent of inheritance of alleles on the other. A strong nonrandom association between the inheritance of alleles at loci on both chromosomes is found among male offspring, while independent assortment occurs among female offspring. We also provide evidence that the mechanism by which this phenomenon occurs involves preferential cosegregation of nonparental chromatids of both chromosomes at the second meiotic divison, after the ova has been fertilized by a C57BL/6 sperm bearing a Y chromosome. These observations confirm the influence of the sperm in the segregation of chromatids during female meiosis, and indicate that a locus or loci on the Y chromosome are involved in this instance of meiotic drive.
