Hypothesis vs Theory - hypothesis is and educated guess while a theory is concept that is well supported by observation, experiments, and data. Hardy-Weinberg - No migration, choice of mates random, mutation does not occur, no selection pressure Adaptive radiation - a population colonizes a new habitat and go through natural selection, adapt and become new species (finches). allopatric - isolated population become new species. (porkfish landbridge) Alveolata - Ciliates and dinoflagellates...

When Thomas Hunt Morgan crossed his red-eyed F1 generation flies to each other, the F2 generation included both red- and white-eyed flies. Remarkably, all the white-eyed flies were male. What was the explanation for this result? - ANSWER The gene involved is on the X chromosome. Which of the following is the meaning of the chromosome theory of inheritance as expressed in the early twentieth century? - ANSWER Mendelian genes are at specific loci on the chromosome and, in turn, segregate duri...
