Two researchers experimentally formed tetraploid frogs by fertilizing diploid eggs from rana porosa brevipoda with diploid sperm from rana nigromaculata. when they mated these tetraploid frogs with each other, most of the offspring that survived to maturity were tetraploid, with chromosome sets of both diploid parent species. based on these results, if this type of tetraploid formed in the wild, what would be the result?

In the given case, if the tetraploid gets formed in the wild, then the tetraploids would be reproductively isolated from both the parent species.

The mechanisms of reproductive isolation refer to the accumulation of the evolutionary mechanisms, physiological and behavioral procedures perilous for speciation. They inhibit the members of distinct species from generating offspring or make sure that any offspring are sterile.

These obstructions sustain the veracity of the species by minimizing the flow of gene among the associated species.
