Two small ponds have similar frogs that breed in early spring. scientists
were interested in what was occurring to these groups of frogs during
rainy years (flooding) and dry years. they noticed during the rainy years
the frogs would migrate from one pond to the next and interbreed. the
offspring were healthy and were capable of breeding themselves in the
next breeding cycle. in dry years, the frogs stayed in their own ponds and
did not migrate to another area. which is likely true?
