Which type of organism is most likely to undergo sympatric speciation by polyploidy?

Plant species that are capable of self-pollination and some degree of asexual reproduction

Explanation:

Complete Question -

Which type of organism is most likely to undergo sympatric speciation by polyploidy?

plant species that are capable of self-pollination and some degree of asexual reproduction

animal species with poor dispersal abilities whose populations exist in widely separated, small patches of habitat

animals, particularly those with highly selective females that select mates based on exaggerated traits

plant species that are incapable of asexual reproduction and do not self-pollinate

Solution -

Sympatric speciation occurs when a group of organisms living in a habitat become reproductively isolated from each other. It generally occurs through polyploidy in which offspring with more than the normal number of chromosomes are produced. However, a normal individual exhibit diploidy (i.e with two copies of each chromosome). Individuals with different number of chromosomes cannot mate thereby creating reproductive isolation. Sympatric speciation occurs in plants because they can self-fertilize which is not the case with the animals.  

Thus, correct answer is "Plant species that are capable of self-pollination and some degree of asexual reproduction"

it is prolly d and c and f
