WebWhich of the following best describes why isolation is a necessary first step in the process of speciation? Group of answer choices A) Because gene flow tends to make populations more genetically homogeneous, genetic differentiation due to forces such as selection or drift requires that gene flow is reduced or eliminated via isolation. WebSpeciation. Alfred Russel Wallace created pioneering work in speciation; however, additional evidence over time has led to our current understanding of the theory of …

Gene flow between individuals on either side of the barrier is stopped.
WebModes of Speciation The 2 stage process of speciation is realized in 2 ways, or modes: geographic and quantum speciation. Geographic Speciation: Stage 1: Starts with the … WebHg derivatisation for speciation analysis. Hg speciation was performed on accurately weighed petroleum hydrocarbon samples (approx. 1 g), which were diluted in 1 mL of o-xylene and derivatised immediately. First, 200 µL of 2 M Grignard reagent (BuMgCl in this work) was added into the sample and mixture was let to react for 5 min.
