However, because of their overuse and misuse, some pathogenic bacteria have become resistant to some of these treatments. When multiple environments favor the existence of a trait, these beneficial traits can pop up through mutation and spread throughout their individual populations completely independently. In order for evolutionary changes to occur, many generations over thousands to millions of years are often required - meaning, these adaptations dont happen overnight!

Suppose you are heterozygous for two genes that are located on different chromosomes. The ability of humans to digest lactose as adults is a perfect example of this. There are three different types of breeds that exist: One advantage to choosing cross-breeds and mixed-breeds over purebred dogs is that harmful genetic mutations that tend to frequently occur in certain lineages can be covered up, or bred out, by the genetic background of the other dog breed(s) in the individual.

Suggested answer: Natural selection is the process by which favorable traits are passed down through different generations of a species in order to adapt and likely survive within the changing environment. These tubes, or chimneys, belch out what looks like black smoke, all. Populations have genetic variation. Natural selection explains how organisms in a population develop traits that allow them to survive and reproduce. If the organisms of a, species cannot change along with the area in which they, live, they risk dying out. The mouse with the mutation will survive and reproduce, and the trait will spread over future generations. - a genetic mutation in an individual that causes it to be very small A method of using biological control to control pests is to The species is naturally selected.
