Why natural selection acts on the phenotype rather than genotype?
natural selection is a passive prosess . the mechanism of some individuals to be selected more than others is because they fit their environment more. and phenotype shows the fitness .
Which does natural selection affect populations or individuals?
Populations evolve, but individuals are selected. Natural selection affects individual organisms.
Natural selection requires that individuals in a population are?
Natural selection requires that individuals in a population are
What is the process by which individuals that are better adapted to their environment survive and reproduce more successfully?
Natural Selection is a process which individuals are better adapted to their enviorment are more likely to survive and reproduce. Say there are turtles barely hatching and there are hungry seagul waiting to be fed, the fastest ones will make it to the water safely while the slow ones are being eaten. so eventually all the turtles in the sea will become faster to get away from predators. hopefully that answered your question.
How does natural selection enable populations to grow?
The growth or shrinkage of populations has nothing to do with natural selection, but with the availability of resources, and the ability of organisms to utilize those resources. This is also known as 'carrying capacity'. The natural tendency is for organisms to produce more offspring than the environment can support. So if the environment supports more individuals, then the population will automatically grow. If conditions change and the environment supports less individuals, then some individuals will starve or be otherwise unable to reproduce. Natural selection, in this case, "determines" which individuals pass, and which do not.
Does selection operate on the genotype or the phenotype?
Natural selection operates on the phenotype.
What does natural selection directly work on?
Natural selection acts on the genotype, but indirectly, through the phenotype.
Why natural selection acts on the phenotype rather than genotype?

Why does natural selection work on organisms phenotypes rather than their genotypes?
This is backward, natural selection works on genotype not phenotype.

The process by which individuals that are better adapted to their environment are more likely to survive and reproduce is called?
natural selection
The idea that organisms with a particular genotype will have better reproductive success than organisms with a different genotype is called?
Sexual selection is a type of natural selection resulting from variation in the ability to obtain mates.
Three ways natural selection picks a phenotype?
stabilizing selection: when individuals near the center of the curve have a higher fitness than individuals at either end of the cure, keeping the center at its current location but narrows the overall graph directional selection: when individuals at one end of the curve have a higher fitness than individuals at the other end, or middle, causing the entire curve to move as the character trait changes disruptive selection: when individuals at the upper and lower ends of the curve have higher fitness than individuals near the middle, causing the single curve to be cut into two These three types of selection are brought about by natural selection, so whichever one is favored, then the genes evolve in that specific direction. natural selection acts on the genotype, but the results are seen in the phenotype
How are phenotypes and genotypes related to natural selection?
Natural selection favours phenotypes that bestow a reproductive advantage, thereby increasing the frequency of alleles (genotype) producing those phenotypes.
How can a wide range of phenotypes increase the chance that some individuals will survive in a changing environment?
by natural selection.
