Can linked genes recombine
WebSex Linkage. Sex linkage applies to genes that are located on the sex chromosomes. These genes are considered sex-linked because their expression and inheritance patterns differ between males and females. While sex linkage is not the same as genetic linkage, sex-linked genes can be genetically linked (see bottom of page). In eukaryotes, recombination during meiosis is facilitated by chromosomal crossover. The 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. It also allows sexually reproducing organisms to avoid Muller's ratchet, in which the genomes of an asexual population tend to accumulate more …

WebHowever small pieces of RNA (sRNA, 20-40 nt) can and do enter the nucleus and are considered master regulators of gene expression. RNA is extremely delicate and typically held at -80. WebPAR1 and PAR2 recombine during meiosis with their homologous regions on the X chromosome, although with different dynamics, compared with the rest of the genome . Indeed, genes located within the PARs are inherited, and genetically behave similarly to autosomal genes. ... Here we recapitulate results that Y-linked genes may affect male ...
