What is gene flow?

• A change in the gene pool due to chance

• A reduction in populations caused by natural disasters, disease, and hunting

• The addition or removal of genes due to individuals entering or leaving the population

• A change in gene frequencies when a new population arises from a few individuals

When Christopher Columbus came to the Americas, he randomly chose 3 chickens from Spain to bring along. These 3 chickens were the only chickens to breed in the Americas for hundreds of year.

• Natural Selection

• Bottleneck

• Founder Effect

A drastic reduction in the size of a population that can change allele frequencies is called

• the bottleneck effect

• the founder effect

• the gene flow effect

• the Thanos effect

• It dies, cannot reproduce and DNA cannot be passed on

• It changes its traits to adapt and survive

• It survives, reproduces and passes on its DNA

There are two types of beetles: red beetles and green beetles. The beetles live in a forest full of trees. The birds in the forest seem to be eating ONLY the red beetles. The green beetles are not eaten. Which phenotype is favored and why?

• The green beetles because they stand out the most

• The red because they are more delicious so they are eaten more

• The red beetles because are not as big

• The green beetles are favored because they blend in with the trees

During the dry season, when water is low, an elephant will dig holes to find underground springs, drawing as much as two gallons at a time with its trunk. The water holes also give elephants access to important mineral sources buried deep below the surface.

• Overproduction of offspring

• Struggle to survive

• Inherited variation

• Non-random mating
