Srry I had to make 2 questions, this website won't show you your own questions
1. populations.
2. Natural selection does not change the alleles an organism has.
3. a mutation causes a specific advantage within the population
4. Brown fur will become predominant.
5. the proportion of different traits in a population
ur welcome
A human is right!!!!!!!!!
Thanks @A Human
Natural selection causes changes in populations, phenotypes, and genotypes.
To understand how natural selection works, let's break it down step by step:
1. Natural selection acts on populations: Natural selection is the process by which populations of organisms with certain traits are more likely to survive and reproduce than others. By favoring individuals with beneficial traits, it leads to an increase in the frequency of those traits within a population over time.
2. Natural selection affects phenotypes: Phenotype refers to the observable characteristics or traits of an organism. These traits can involve physical features like body size, coloration, or behavior. Natural selection can influence the frequencies of different phenotypes within a population, favoring traits that enhance an organism's chances of survival and reproduction. As a result, individuals with advantageous phenotypes are more likely to pass on their genes to the next generation.
3. Natural selection acts on individuals: While natural selection operates at the population level, it happens through the selection of individuals within that population. Those individuals with traits that increase their reproductive success or survival are more likely to pass these traits onto their offspring, thereby increasing the frequency of these traits in subsequent generations.
4. Natural selection affects genotypes: Genotype refers to the genetic makeup of an organism, including the combination of alleles (alternative forms of genes) it carries. Since phenotypes are determined by genotypes, natural selection can influence the frequency of different genotypes within a population. Beneficial mutations or genetic variations that improve an organism's fitness are more likely to be passed on to future generations, leading to an increase in the frequency of those genotypes.
In summary, natural selection acts on populations, affecting the phenotypes of individuals within those populations, which, in turn, are determined by their genotypes.
