6. There are two isolated populations - Population 1 and Population 2. These populations have been separated for a long period of time. Now, imagine that you bring individuals from these populations together to see if they will interbreed. You find that there is only limited interbreeding between Population 1 and Population 2 and the hybrid offspring have lower fitness. Should we classify Population 1 and Population 2 as two different species?
Yes, they are separate species.
No, they are still the same species.
No, they are the same species, however they are in the process of becoming two separate species.
5. Founder effect
On a molecular genetics level, genetic divergence is due to changes in a small number of genes in a species, resulting in speciation. ... Genetic divergence between related populations sometimes start by genetic bottleneck, and founder effects.
6. No They are the same species they are in the process of becoming a separate species.
Based on the "Allopatric Speciation" video, which of the following can lead to genetic divergence?
24. Parapatric speciation would be expected to occur most often: a. in the same homeland b. near a common border between two populations c. within a group of interbreeding populations d. across obvious geographical barriers e. by divergence from a common interbreeding population 25. Match the evolution concepts: _______ gene flow a. can lead to interdependent species _______ natural selection b. changes in a population's allele frequencies due to chance alone _______ mutation c. alleles enter or leave a population _______ genetic drift d. evolutionary history _______ adaptive radiation e. occurs in different patterns _______ coevolution...
1. A population of monkeys on an island in the Amazon river is preyed upon by margays (a type of small cat). Within this population the largest monkeys are too big for the margays to catch and the smallest monkeys are too agile for the margays to catch. Thus the mid-size monkeys have the lowest fitness. Over time this population could potentially split into two populations and two separate species of large and small monkeys. What type of speciation would occur...
Of the following evolutionary forces; crossing over, directional selection, mutation, speciation, stabilizing selection, sex, gene flow and genetic drift which promote or maintain genetic variation within a population? a) crossing over only b) directional selection and sex c) directional selection, mutation, and speciation d) crossing over, mutation, sex, and gene flow e) only sex Of the following evolutionary forces, crossing over, directional selection, mutation, speciation, stabilizing selection, sex, gene flow and genetic drift which promote genetic differentiation (divergence) among populations?...
Which condition can lead to two populations becoming different species? all of these A barrier to gene flow exists between the two populations. Individuals in the two populations have significant genetic differences from one another. Individuals may live in geographically isolated areas. Individuals in the two populations mate at different times. Which of these is NOT an example of adaptive evolution? bottleneck all of these gene flow founder effect Mutation Which of these does NOT influence allele frequencies in a...
QUESTION 5 Which of the following would best be described as a case of speciation due to dispersal? Two populations of mice diverge in their phenotype and genotype due to adaptation to two different A. soil colors In a lake, a population of fish diverges in their phenotype and genotype because the fish pick mates based on OB. their color A new, isolated population of fruit flies is founded on an island, which then diverge from the OC. parent population....
24. Which of the following species concepts is defined by populations of interbreeding individuals that are reproductively isolated from other populations? A. phylogenetic B. ecological C. biological D. morphologicalOn the Bahamian Island of Andros, mosquitofish populations live in now-isolated, freshwater ponds that were once united. Currently, some predator-rich ponds have mosquitofish with a body shape that allows them to swim in short, fast bursts. Other predator-poor ponds have mosquitofish with a body shape that allows them to swim continuously for a...
please help me with these questions. i cant post anymore and im studying for my exam. thank you in advance A flock of birds which are blown of course and end up on an unpopulated island could be an example of: Vicariant Speciation a Founder Event A Bottleneck Natural Selection Which of the following is NOT one of the five theories of Darwinism (Mayr)? Survival of the fittest Gradualism Common descent Perpetual Change Multiplication of species Which of the following...
1) Darwin's four postulates include (circle all that apply) a) Reproductive success and survival are NOT predictable b) There is variation in a population c) Some trait differences in a population are heritable and are passed from generation to generation d) Individuals with certain traits are more likely to survive and reproduce e) All of the above are Darwin's postulates. 2) For each of the following, indicate whether the statement is True or False (circle correct choice) a) An adaptation is a behavior...
16. Which mode of natural selection is demonstrated by the Ginkgo tree today remaining essentially similar morphology since the Mesozoic era? a. stabilizing b. directional c. diversifying d. sexual e. artificial 17. Which scenario will demonstrate disruptive (diversifying) selection? a. There is heterozygote advantage (heterozygous individuals have the highest fitness). b. Female flies collect sperm from different males in her sperm bag. c. Individuals with intermediate phenotype are inferior competitors against homozygous individuals d. Insects become resistant to the most...

None of these Aristotle is noted for developing the concept of ........ a. Essentialism/Idealism b. Punctuated Equilibrium c. Scala Naturae d. Catastrophism e. The Inheritance of Acquired Characteristics What are vestigial structures? a. These are structures that have different origins that perform thesame task. b. These are structures of the same origin that may look different...
