Two populations of catfish have lived in separate neighboring lakes for many generations. Population A contains about 30% short whiskered catfish (ww) and 70% long whiskered catfish (WW or Ww); Population B contains about 10% short whiskered catfish and 90% long whiskered catfish. Following a year of record rainfall, both lakes rise enough to allow the catfish populations to swim between the two lakes and interbreed. What will be the effect(s) over time of this interbreeding?
_____ DIfferences in the frequencies of W and w between the two populations will increase. _____ Population A will see an increase in long whiskered fish, but Population B will not see any changes in the prevalence of the two phenotypes. _____ Population A will see an increase in long whiskered fish and Population B will see an increase in short whiskered fish. _____ Population B will see an increase in short whiskered fish, but Population A will not see any changes in the prevalence of the two phenotypes. _____ DIfferences in the frequencies of W and w between the two populations will decrease. _____ Population A and Population B will experience an increase in genetic diversity.
