Evolution-Exam 2 questions and answers 100% guaranteed success. genetic drift - correct es genetic variation results from random sampling faster rate in a small pop (alleles become fixed) genetic bottleneck - correct genetic drift by drastically reducing population size rare alleles are likely to be lost ie elephant seals founder effect - correct answers.a type of genetic drift random sampling founding a new population with very few individuals new popu...

BIOL 3040 STUDY GUIDE II, PART A Chapter 4 Synapomorphy: A character or trait that is shared by two or more taxonomic groups and is derived through evolution by a common ancestor. Homoplasy: Correspondence between parts or organs acquired as a result of parallel evolution or convergence. Homoplasy is analogous and can be due to convergent evolution 1. According to the tree below: a Species B is more closely related to species G than species A b Species B is equally related to specie...

Why might Pasteur's experiment be inconclusive? - ANS - The swan-necked flask broth may not support cell growth, or the broth was poisoned. Experiment did not confirm hypothesis that all cells come from pre-existing cells Why are replicates important in experiments? - ANS - To ensure that results were not achieved by random chance What is the definition of a replicate? - ANS - Unit that shares a common thing (4 mice in one cage = 1 replicate) What does the law of succession sugge...
