The genetic mechanisms that decrease a population's chances for adaptation and survival are the Founders effect and the Bottleneck effect.
Explicación
## Step 1The question asks us to identify the genetic mechanisms that decrease a population's chances for adaptation and survival. The options provided are: Random genetic mutations, Founders effect, Gene Flow, Bottleneck effect, and Natural Selection.## Step 2Random genetic mutations are changes in the DNA sequence that occur randomly. While some mutations can be harmful, others can be beneficial and increase the population's chances for adaptation and survival.## Step 3The Founders effect is a type of genetic drift that occurs when a small group of individuals is isolated from the rest of the population. This can lead to a decrease in genetic diversity, which can decrease the population's chances for adaptation and survival.## Step 4Gene Flow is the transfer of genetic variation from one population to another. This can increase the genetic diversity of the receiving population, which can increase the population's chances for adaptation and survival.## Step 5The Bottleneck effect is a type of genetic drift that occurs when a population is drastically reduced in size. This can lead to a decrease in genetic diversity, which can decrease the population's chances for adaptation and survival.## Step 6Natural Selection is the process by which organisms that are better adapted to their environment tend to survive and produce more offspring. This can increase the population's chances for adaptation and survival.
