Question

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

Answer 1

Answer:

They are allotetraploids

Explanation:

The resulting progeny possess 4 pairs of non-homologous chromosomes (4n). These organisms are generally fertile, they are formed by the fusion of 2 diploid gametes of different species. A well know example of allotetraploid species is Triticale, which is an allotetraploid hybrid formed by wheat and rye
