The genetic mechanisms that decrease a population's chances for adaptation and survival are the Founder's 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 chances of adaptation and survival. Therefore, random genetic mutations do not necessarily decrease a population's chances for adaptation and survival.## Step 3The Founder's effect is a type of genetic drift that occurs when a small group of individuals becomes isolated from the larger population. This can lead to a decrease in genetic diversity and can negatively impact the population's ability to adapt and survive.## Step 4Gene flow is the transfer of genetic material from one population to another. This can increase genetic diversity and improve the population's ability to adapt and survive.## 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 loss of genetic diversity and can negatively impact the population's ability to adapt and survive.## Step 6Natural selection is the process by which organisms that are better adapted to their environment tend to survive and produce more offspring. This process can increase the population's ability to adapt and survive.
