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. 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 … cummings amendmentWebmanifestation of a characteristic specified by a gene. principal of dominance. states that some alleles are dominant and others are reccesive.

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).
