The reason that finding might matter to us, is that recent studies in mice and zebra fish have shown that hearts with more diploid cells—like a zebra fish's—are able to regenerate and heal themselves.

这一发现可能对我们很重要的原因是,最近对小鼠和斑马鱼的研究表明, 具有更多倍体细胞的心脏(如斑马鱼的心脏)能够再生和自我修复。

染色体倍性 Ploidy

(重定向自Diploid)

染色体倍性是指细胞内同源染色体的数目,只有一组称为「单套」或「单倍体」(haploid),两组称为「双套」或「二倍体」(diploid)。

多倍体又分异源多倍体(Allopolyploidy)和单源多倍体(Autopolyploidy),前者的染色体来自不同种。

在双套生物中,有一个过程,将双倍体的细胞分裂成单倍体,使配子结合后的合子为双倍体,称为减数分裂。

有些生物以倍性来作决定性别:雌性为双倍体,雄性为单倍体。

有些生物是多倍体(polyploid),有多于两套染色体,譬如金鱼、鲑鱼、蚂蟥、扁形虫、有尾目和蕨类植物。多套的动物通常都是低等动物,孤雌生殖居多。

Ploidy 染色体倍性

(重定向自Diploid)
Diploid cells have two homologous copies of each chromosome.

Ploidy is the number of sets of chromosomes in a cell. Usually a gamete (sperm or egg, which fuse into a single cell during the fertilization phase of sexual reproduction) carries a full set of chromosomes that includes a single copy of each chromosome, as aneuploidy generally leads to severe genetic disease in the offspring. The gametic or haploid number (n) is the number of chromosomes in a gamete. Two gametes form a diploid zygote with twice this number (2n, the zygotic or diploid number) i.e. two copies of autosomal chromosomes. For humans, a diploid species, n = 23. A typical human somatic cell contains 46 chromosomes: 2 complete haploid sets, which make up 23 homologous chromosome pairs.
