Summary Introduction
To explain: How the differences of sexual selection in strawberry poison dart frogs (Dendrobates pumilio) could arise and affect the evolution of reproductive isolation in allopatric versus sympatric populations.
Concept introduction:
Strawberry poison-dart frogs (Dendrobates pumilio) are found in Central America mainly in the Costa Rica and adjacent mainland of Panama. Pumiliotoxin which is the main toxin in these frogs is due to their dietary intake of formicine ants. These frogs exhibit an amazing array of color variation which is considered to be the basis of intraspecific male mating calls which lead to ultimately fall the entire population into one species.

- explain the following : 1. Does chromosome structure differ between humans and their closest relative among the apes. 2.How can natural selection promote reproductive isolation in allopatric populationsarrow_forwardn which situation would it make sense to use the morphological species concept? When you are able to collect data about how individuals in your study use their habitat, but you are unable to determine if they interbreed When working with fossils from extinct organisms When you only have genetic data about each organism in your study When you are not able to collect data about how individuals in your study use their habitat, but you are able to collect reproductive dataarrow_forwardWhich of the following forms of reproductive isolation illustrates a prezygotic barrier to gene flow? O Species A forms hybrids with species B and the hybrids are able to breed back with either of the two parent species to produce healthy fertile offspring. O Two closely related birds, the lazuli bunting and indigo bunting, sing similar songs to attract mates and even though human ears can not distinguish them the females never make wrong choices in choosing who to mate with. O Two species of turtles living in a large lake have different ecological requirements and never interact. O Several species of corrals in a Honduras corral reef release gametes about the same time but inter- specific attraction of gametes does not occur. O All but one of these illustrates a type of prezygotic barrier to gene flow.arrow_forward

Beetles from two geographically isolated populations are captured and brought to the lab. When an adult male from one population and an adult female from the other population are placed together, they mate, and the female lay eggs a couple of days later. The eggs hatch, the beetles develop into adults but are sterile. Which of the following are true? This is an example of post-zygotic reproductive isolation. O Sexual selection is likely responsible. O This is an example of pre-zygotic reproductive isolation. O Dobzhansky-Muller genetic incompatibility is likely responsible. Question 3 Choose all that apply. Which of the following are true of adaptive radiations? OAdaptive radiations involve relatively rapid speciation. The evolution of the Hawaiian silverswords is an example of an adaptive radiation. OAdaptive radiations can occur when an ancestral species colonizes a new arca and adapts to multiple open niches.
