Accepted Answer

Hello everyone here we have a question saying, hey with France, the robert C. Is a sterile tri pointe hybrid between ego tata and elude idea. Since it has an abnormal number of chromosomes, it cannot interbreed with its deployed ancestors. This type association is considered a alot polyp oid be auto polyp Lloyd C. Ala patrick or D. Perry patrick. In this case speciation is not caused by a geographic barrier but due to paul ploy D. So it is a sim patrick type of speciation because it involves the hybridization of two different species and produces a third species that cannot interbreed with its ancestors. It is considered a low polyp Lloyd speciation. So our correct answer here is a ahlu polyp oid. Auto polyp Lloyd is incorrect because the new species is not produced by doubling the chromosome in the original population. So our answer here is a ala polyp Lloyd. Thank you for watching. Bye.
