Some species undergo polyploidy, which is a multiplication of their chromosomes. That is, they contain full chromosomes from each parent. How could speciation affect a polyploid organism?

Question

A. The polyploid organisms may experience gametic isolation.

B. The polyploid organisms may experience behavioral isolation.

C. The polyploid organisms may experience geographic isolation.

D. The polyploid organisms would not be affected by speciation.

Answer 1

A. The polyploid organisms may experience gametic isolation.

Polyploid organisms may have difficulty reproducing with their non-polyploid counterparts due to differences in the number of chromosomes, leading to gametic isolation and potentially contributing to the process of speciation.
