A forest was converted into a national park. This process required constructing roads and highways to make it accessible for peo
ple. Construction of roads inside a forest has resulted in 1.fragmentation 2.increased biodiversity 3.restoration of natural habitat. A large population of organisms was split into several smaller populations, which decreased the chance that an individual would 1.inbreed 2.find an unrelated mate 3.compete for a mate . ASAP!!!
Pull down menu 1: fragmentation Pull down menu 2: find an unrelated mate
Explanation:
Building a road through a habitat can split animal populations into separate colonies, leading to "fragmentation." Fragmentation causes animals to breed within a smaller population, which reduces their chances of finding an unrelated mate.
<u>Question 1.</u> 1.fragmentation The roads act as barriers which cannot/or will not be crossed by many forest dwelling species. They are either physical or psychological barriers for animals. The presence of humans and cars further increases this effect. Thus, the original forest habitat becomes fragmented into smaller areas with smaller populations.
<u>Question 1.</u> 2.find an unrelated mate
As the forest becomes fragmented, the original area and population of a species is divided into smaller units. Thus, for the individuals belonging to such a diminished population, the chances of finding an unrelated mate will decrease rapidly with time. This will lead to inbreeding and a loss of genetic diversity.
This type of directional selection is referred to as stabilizing section where the intermediate phenotypes are favored over those of the extreme. It is referred to as stabilizing selection because it maintains the mean phenotype of the population.
