Moreover, balanced rearrangements in individuals … WebChromosomes are thread-like structures located inside the nucleus of eukaryotic cells. Each chromosome is made of protein and a single linear double-helix of DNA. The term chromosome comes from the Greek words for color (chroma) and body (soma).

WebMay 1, 2006 · From its first appearance, the inversion will show underdominant fitness interactions with the chromosomal arrangement that is most common in the other population. In this case, there is no limit to how low the fitness of heterokaryotypes can be. In the extreme, the local adaptation mechanism could fix an inversion that is sterile or …
WebOct 19, 2010 · These rearrangements change the order of genes around the chromosome by translocating and inverting chromosomal regions. In addition, some rearrangements are not tolerated, indicating that there are selective forces that limit genome plasticity. WebThe XXY chromosome arrangement affects primarily sexual development. Typically, testes don't fully develop, and the levels of the hormone testosterone (important for male sexual development) are lower than average. As adults, nearly all XXY males are unable to make sperm and so cannot have biological children.
