A species of fox lives in the arctic where the ground is covered in white snow most of the year. These arctic foxes hunt rodents and other small mammals, while their predators include eagles, wolves, and polar bears. A mutation in its DNA causes a fox to have white fur rather than brown. Given this information, would you classify this mutation as a harmful, beneficial, or neutral mutation? Would this make the fox more or less likely to survive? Explain your answer.
In this scenario, the mutation causing white fur instead of brown fur in the arctic fox can be classified as a beneficial mutation. This is because the white fur would provide camouflage for the fox in its snowy environment, making it less visible to its prey and predators. As a result, the fox with white fur would be more likely to survive and avoid being hunted by eagles, wolves, and polar bears. The camouflage provided by the mutation increases the fox's chances of successfully hunting rodents and small mammals.
The correct answer is that chromosomes and genes are both part of DNA and they both contain genetic material.
To understand why chromosomes and genes are alike, we need to understand what each of them is.
Chromosomes are structures made up of DNA and proteins found in the nucleus of cells. They are thread-like structures that contain the genetic information of an organism. Humans have 46 chromosomes, with each chromosome containing hundreds to thousands of genes.
Genes, on the other hand, are specific segments of DNA that contain the instructions for making proteins. Proteins are essential molecules that perform various functions in the body, such as building and repairing tissues, regulating chemical reactions, and serving as signaling molecules. Genes provide the instructions that determine the characteristics and traits of an organism.
So, both chromosomes and genes are part of DNA and contain genetic material that determines the characteristics of an organism.
