Sperm genomes also manifested many genomic anomalies that could not be explained by simple nondisjunction. Diverse recombination phenotypes—from crossover rates to crossover location and separation, a measure of crossover interference—covaried strongly across individuals and cells. Our results can be ...
Describe how the law of segregation and the law of independent assortment can be explained by meiosis. Explain (not list) two ways sexual reproduction, including meiosis, can cause offspring to be genetically different from their parents. How is karyotyping re...
In this model, the shift to an entirely equational segregation pattern in spo13Δ spo11Δ mutants can be explained as follows. Initially, kinetochores are cooriented in spo13Δ spo11Δ mutants but, due to the absence of a physical linkage between the homologs, tension is absent. The lack ...
The loss of the central signal in mouse hybrids, in Dmc1–/– mice, and on the WT non-PAR X chromosome could potentially be explained if DSB repair is delayed. With a fixed on/off rate for PRDM9, the longer DSBs persist, the more time MRE11 may have to process and remove SPO11-...
The process of gamete formation in meiosis explainedGametes are formed through meiosis (reduction division). See all videos for this article The process of meiosis is characteristic of organisms that reproduce sexually. Such species have in the nucleus of each cell adiploid(double) set of chromosome...
This is likely explained by the direct phosphorylation of a CPC component by CDK-1, as observed in mitotic cells49. Coupling REC-8 phosphorylation to the maturation process that releases oocytes from their developmental arrest before the first meiotic division may promote correct chromosome segregation...
