Sympatric speciation does not require geographical isolation; mutations, such as polyploidy, can lead to reproductive isolation and new species formation, especially if the polyploid organism reproduces asexually.
Speciația simpatică nu necesită izolare geografică; mutațiile, cum ar fi poliploidia, pot duce la izolare reproductivă și formarea unei noi specii, mai ales dacă organismul poliploid se reproduce asexuat.
| Front | Sympatric speciation |
|---|---|
| Back | Doesn't require geographical isolation Mutations can increase the number of chromosomes (polyploidy) Individuals with different number of chromosomes cant reproduce and so they become reproductively isolated If the polyploidy organism reproduces asexually then a new species can emerge Polyploidy can only lead to speciation if it doesn't prove fatal |
