Well I'm not smart either. But i'll give you the answer.
Explanation:
Since the population of gray squirrels and brown squirrels decreased, and the population of black squirrels increased, that means the gray and brown squirrels were eaten/left and didn't blend in very well to their habitat. However, the population of black squirrels increased, so they blended in well with their environment. This tells us that the color of the trees became darker, closer to black, since there were more of them.
Answer: in explanation
Explanation:
Over time the color of the trees changed to black or a dark color. Because the color of the trees changed the gray and brown squirrels were more noticeable to the foxes causing them to be killed off. This meant over time the squirrells with black fur survived and bred eventually populating the area with black squirrells.

B. Genetic drift increases the genetic differences between populations.
C. Natural selection, mutation, and genetic drift are random events.
D. The bottleneck effect increases the genetic diversity of a population.
Answer:
Natural selection, mutation, and genetic drift are random events.
Explanation:
A mechanism of evolution in which the frequencies of alleles of a population change with generations because of sampling error is known as genetic drift. It takes place in all the populations of non-infinite size, however, its influences are strongest in small populations.

how are traits passed down from one generation to another
Answer:
Genes & DNA
Explanation:
Heritable traits are known to be passed from one generation to the next via DNA, a molecule that encodes genetic information.Organisms inherit genetic material from their parents in the form of homologous chromosomes, containing a unique combination of DNA sequences that code for genes.
Answer:
Traits are passed down from one generation to another because of DNA.
Explanation:
Genetic inheritance occurs due to genetic material, in the form of DNA, being passed from parents to their offspring. When organisms reproduce, all the information for growth, survival, and reproduction for the next generation is found in the DNA passed down from the parent generation.
