selection of traits is where you select what you want to your baby to or not too look like
no, inherited traits are responsible for natural selection
Natural selection and artificial selection both involve an organism's traits being determined by how much they're favored. Then, the organisms with favorable traits pass those traits on to future generations.However, natural selection is caused by survival; the organisms with traits that increase their chances for survival and reproduction pass on their traits. As for artificial selection, humans purposefully decide which traits (like the most colorful one) of an organism to pass on.The similarity of artificial selection and natural selection is that they both can cause changes in the frequency of population.
How does natural selection affect undesirable traits?
artificial selection
Positive selection refers to the process in which advantageous traits are favored and passed on to future generations, leading to an increase in their frequency in a population. Purifying selection, on the other hand, eliminates harmful or deleterious traits from a population, reducing their frequency over time. In essence, positive selection promotes the spread of beneficial traits, while purifying selection removes harmful traits from a population.
The process by which humans breed organisms to obtain certain traits is known as artificial selection.
artificial selection
Positive selection pressure favors traits that increase an organism's chances of survival and reproduction, leading to the evolution of beneficial traits. Negative selection pressure, on the other hand, eliminates traits that decrease an organism's chances of survival and reproduction, resulting in the removal of harmful traits from a population. Overall, positive selection pressure drives the evolution of advantageous traits, while negative selection pressure helps to maintain the fitness of a species by removing detrimental traits.
The process of purifying selection removes harmful traits from a population, while positive selection promotes the spread of beneficial traits. Purifying selection reduces genetic variation by eliminating harmful mutations, leading to a more uniform population. Positive selection, on the other hand, increases genetic diversity by favoring advantageous traits, which can lead to the evolution of new characteristics in a population.
Greater genetic variability results in better selection for a stable character
Natural selection can lead to extreme traits in a population if those traits provide a significant advantage in survival or reproduction. Genetic drift can also lead to extreme traits if there are random fluctuations in the frequency of alleles in a population. Additionally, sexual selection can drive the evolution of extreme traits if individuals with those traits are preferred as mates.
Natural selection requires variation in traits within a population, heritability of those traits, and differential reproductive success based on those traits. Without these components, natural selection cannot act on a population.
