I just studied how autopolyploids and allopolyploids form and would greatly appreciate if someone could clarify something for me.
From what I understood autopolyploids form from the fusion of diploid gametes from diploid parents. Allopolyploids form when haploid gametes from two different species fuse, followed by spontaneous doubling of chromosomes.
In both cases a tetraploid organism is formed but the stage at which the the chromosomes doubles for autopolyploids and allopolyploids is meiosis and mitosis respectively.
Is what I have written correct?
Thanks in advance.
