a flowering plant that produces a polyploid cell that can self-fertilize and produce a new species

A) directional selection
B) sexual dimorphism
C) sympatric speciation
D) balanced polymorphism
E) coevolution
F) allopatric speciation
G) key innovation
H) adaptive radiation

Sympatric speciation is the process by which a new species arises from a single ancestral species while inhabiting the same geographic region. This can occur through various mechanisms, such as polyploidy, where a cell or organism has more than two sets of chromosomes, allowing it to self-fertilize and produce a new species.
