Speciation
Here are some additional links on the topic of speciation:
In sympatric speciation, 2 diploid gametes can fuse to form a tetraploid.
If it is autotetraploid, then all 4 of each kind of chromosome try to pair up during meiosis 1. Am i right?
When alloteraploids undergo meiosis 1, 2 chromosomes from one species pair up with each other, while another 2 chromosomes from the other species pair up. Therefore, less muddled situation. So is the resulting gamete for the allotetraploid a haploid or diploid?
wow! can it be that one of my 609 is actually asking me a question here? ;p hi adelyn, you're right with everything you said. as for the gamete, it'll be diploid.
With a long way to Christmas my true love gave to me,

*shakes and scratches balding head* why am i not surprised. :)

Sir, i have a question.
