The difference between allopatric and sympatric speciation is how long it takes for populations to split into separate species.
Polyploidy creates individuals or gametes with novel numbers of chromosomes. To mate, these individuals must mate with other organisms that are also polyploid. Would this lead to polyploidy being more common in animals or plants, and why?
Animals. Animals tend to have mobile sperm, so the gametes can travel farther to find compatible eggs.
Plants. Many plants can self-fertilize, and gametes from the same plant will have the same number of chromosomes.
Animals. Animal species are more likely to have individuals that are only one sex.
Plants. Plant ovules tend to be larger than animal eggs meaning they can better accommodate the extra DNA.
