Which statement is accurate about natural selection?(1 point)
Responses
Natural selection cannot inactivate genes.
Natural selection does not change the alleles an organism has.
Natural selection does not impact reproduction rates.
Natural selection cannot occur through mutations.
Which of the following is an example of natural selection
A population of giraffes with longer necks surviving and reproducing better than a population of giraffes with shorter necks, allowing the genes for longer necks to become more prevalent in the population over time.
To determine which statement is accurate about natural selection, we will discuss each option and evaluate its accuracy.
1. Natural selection cannot inactivate genes: This statement is not accurate. Natural selection can indeed lead to the inactivation of genes. If a particular gene or allele does not provide any survival advantage or is detrimental to an organism's survival and reproduction, it is likely to be selected against, leading to its inactivation over time.
2. Natural selection does not change the alleles an organism has: This statement is not accurate. Natural selection is a driving force of evolution that acts on genetic variation within a population. Through natural selection, certain alleles that confer advantages to an organism's survival and reproduction are more likely to be passed on to future generations, thus changing the allele frequencies in the population.
3. Natural selection does not impact reproduction rates: This statement is not accurate. Natural selection has a significant impact on reproduction rates. The fundamental principle of natural selection is that individuals with traits that increase their chances of survival and successful reproduction are more likely to pass on their genes to future generations. As a result, traits that enhance an organism's reproductive success become more common in a population over time.
4. Natural selection cannot occur through mutations: This statement is not accurate. Mutations are a source of genetic variation, and natural selection acts upon this variation. Mutations can introduce new alleles into a population, and if these mutations confer a survival advantage, they may be favored by natural selection. Conversely, if a mutation is harmful, it may be selected against and decrease in frequency within a population.
Based on the evaluation, none of the provided statements are accurate about natural selection.
