| 1 | There are two kinds of hybrid speciation: homoploid and polyploid . | |
| 2 | Sublethal temperature might be suitable for polyploid inducement of cold shocks. | |
| 3 | The main exceptions to this are hybrid and polyploid speciation. | |
| 4 | In vertebrates, polyploidy tends to be lethal, but plants can do just fine with all this extra genetic material. | |
| 5 | Genetic analysis was conducted on genome DNAs from 15 polyploid sugarbeet varieties by RAPD markers. |
