Two Researchers Experimentally Formed Tetraploid Frogs by Fertilizing Diploid Eggs

question 65

Multiple Choice

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?

• A) The two parent species would interbreed and fuse into one species.
• B) The two parent species would recognize each other as mates.
• C) The tetraploids would be reproductively isolated from both parent species.
• D) The tetraploids would be selected against.
