Crossing over only occurs during meiosis I. Independent Assortment and Linked Genes Independent assortment allows genes to be inherited independently, contributing to diverse traits in offspring. Siblings often inherit different gene combinations from their parents because of this process. However, there ...
There are scenes intercut across other episodes, linking and crossing-over into one another without you realising. thequietus.com In meiosis, the process of crossing-over occurs between non-sister chromatids, which results in new allelic combinations of a population. ...

During his studies, Winge also observed in this species an unusual segregation pattern of two cell morphology markers [34]. The subsequent interpretation by Lindegren was that the two genes were not linked and that “each is so close to the spindle attachment that segregation invariably occurs at...
A process similar to crossing-over can be utilized in somatic cells to repair DNA that has a double-stranded break. It is called homologous recombination. Once a double-stranded break occurs, nucleases 'digest' or eat away at the broken ends of DNA so that new DNA can be added, b...
