During crossover in biology
WebCrossover allows the chromosomes you pass to your children to have some genes from your mother and some from your father. Without crossover each chromosome you passed to your offspring would either be exactly the same as the one from your mother or exactly the same as the one from your father. 1 comment ( 13 votes) Upvote Downvote Flag more WebApr 14, 2014 · In eukaryotic cells (those with a defined nucleus), crossing over can also occur during mitosis.

WebThe crossover process leads to offspring having different combinations of genes from those of their parents, and can occasionally produce new chimeric alleles. The shuffling of genes brought about by genetic recombination produces increased genetic variation. WebDietary fibers can affect appetite and gut metabolism, but the effect of the novel potato fibers FiberBind and rhamnogalacturonan I (RG-I) is unknown. We, therefore, aimed to investigate the effect of daily intake of FiberBind and RG-I on appetite sensations and fecal fat excretion.
