Which could lead to allopatric speciation by two populations of snail? Group of answer choices A. creation of a new mountain range between two populations B. a mutation in all members of one population which prevents gamete fusion between the two populations C. a change in breeding time of one population D. a change in mating behavior in one population but not in the other
Vicariance describes a fundamental process preventing gene flow which is part of Select one: a. sympatric speciation b. parapatric speciation c. allopatric speciation
What is Sympatric speciation? A) When a population is separated from the main group by a barrier and becomes a new species B) When a population mutates into a new species C) When a population develops into a new species without any physical barriers to isolate them
Which variable increases the likelihood of allopatric speciation taking place more quickly? a. lower rate of mutation b. longer distance between divided groups c. increased instances of hybrid formation d. equivalent numbers of individuals in each population
What is Allopatric speciation? A) When a population is separated from the main group by a barrier and becomes a new species B) When a population mutates into a new species C) When a population develops into a new species without any physical barriers to isolate them
Which of the following factors would not contribute toallopatric speciation?(A) The separated population is small, and genetic drift occurs.(B) The isolated population is exposed to different selectionpressures than the ancestral population.(C) Different mutations begin to distinguish the gene pools ofthe separated populations.(D) Gene flow between the two populations is extensive.
JUST ANSWER, DON'T EXPLAIN Microevolution is described by which of the following? Select one: A. Changes in anatomical structures found in an individual when compared to ancestral forms of the species B. Changes in anatomical structures found in a population when compared to ancestral forms of the species C. Changes in the frequency of alleles in a population D. Changes in the frequency of alleles in an individual
Speciation can occur when two populations of a species become separated from each other. What is the best explanation for why speciation occurs?
A physical barrier separates a single species, causing two separate populations to form. Over time these two populations adapt to their environments. Eventually, these two populations are no longer able to successfully reproduce with each other. This is known as __________. A. Sympatric speciation B. Allopatric speciation C. Autopatric speciation D. Parapatric speciation
Which is a criticism of sympatric speciation? A.) many cases of sympatric speciation are actually microallopatry B.) allopatric speciation is less common and scientists should focus more attention on locating additional examples C.) sympatric speciation is only associated with changes in ploidy, a process so rare that it's relatively unimportant D.) since most examples of sympatric speciation involve post zygotic isolation, hybridization nearly always results in their reversal
based on the image attached a) Explain how genetic drift caused egg hatching to decrease in the late 1980s and 1990. b) Why did hatching improve following translocations? c) What are the general effects of gene flow between populations
Please answer fast In an allopatric speciation model, we would expect A Strength of reproductive isolation to increase with increased time in isolation B.Strength of reproductive isolation to increase with decreased time in isolation C .Strength of reproductive isolation to be unrelated to time in isolation D .Strength of reproductive isolation to decrease with increased time in isolation
