Global Winds
Coriolis Effect
Continental Deflection
Answer:
Answer is all of the above.
Explanation:
Reproductive isolation can be described or explained as a collection of mechanisms such as behavioral and ecological mechanisms preventing the members of two or more groups of different species that mate from producing offspring, or if their mating eventually produced offspring, the offspring will not be fertile.
There are things that can make reproductive isolation to occur, they include
* Lack of fit between or among sexual organs.
* Creation of mating location,behavior and time.
* Offspring sterility
Answer:
directional selection
Explanation:
The directional selection is a type of Darwinian selection where a particular phenotype is favored in the population, thereby modifying the allelic frequencies to increase the proportion of the favored phenotype. <em>Biston betularia</em>, also known as peppered moth, is a species that was influenced by directional selection in its recent past. Before the industrial revolution, the frequency of light-colored moths was predominant compared to the darker-colored phenotypes, because this color has higher adaptive fitness in a clean, no pollution environment, thereby light-colored moths were able to avoid predatory birds. However, during the industrial revolution, the frequency of dark-colored moths increased in response to pollution (i.e. darker environment), thereby conferring a higher adaptive fitness to darker phenotypes.
Answer: A alleles
Explanation: this is because they are alternate genes that can make up different traits .
