Chapter 24, Problem 1TYK
Summary Introduction
Introduction: The species in reproductive isolation impedes the members of both the species from interbreeding to the species that produce fertile offspring. These barriers stop the gene flow between the species, and thus limit the formation of hybrids.

- Two species of beetle are physically unable to mate with one another, despite being otherwise morphologically identical, because of the different structure of their reproductive organs. What type of isolating mechanism is involved? Group of answer choices A. behavioral isolation B. gametic isolation C. mechanical isolation D. temporal isolation E. habitat isolationarrow_forwardWhich of the following would be a good example of premating reproductive isolation? A. Cross-fertilizations between the gray treefrogs, Hyla versicolor and H. chrysoscelis result in a high degree of mortality prior to hatching of hybrid eggs. B. The mule, a hybrid between horses and donkeys is viable, but sterile. C. Males of H. versicolor produce an advertisement call with a much slower pulse rate than males of H. chrysoscelis and females use pulse rate differences to avoid mating with the wrong species. D. Hybrid offspring are produced from matings between leopard frogs and green frogs, but usually die before the tadpoles metamorphose into froglets.arrow_forwardWhich of the following traits is more associated with an Opportunistic (Equilibrial) species?

Behavioral isolation C. Habitat isolation D. Mechanical isolationarrow_forwardThe Old Order Amish is a relatively small population of individuals found in the United States in Pennsylvania and Ohio. They are a very isolated population due to their strong religious beliefs and lifestyle that have continued for more than 200 years. They mostly select mates from within their own population, which has had significant effects on their gene pool.The effects on their gene pool is a result of a. non-random mating b. founder effect c. mutation d. bottleneck effectarrow_forwardMembers of two separate species mate and produce hybrid offspring that fail to thrive in the environment. The hybrid genotypes do not suit the hybrid organism for survival using any given niche. Eventually, the hybrid genotypes disappear from the environment.
