According to Neo-Darwinism, natural selection operates through differential reproduction. During sexual reproduction gametes are formed by meiosis division in which crossing over brings about change in traits that leads to variation for natural selection.

According to Neo-Darwinism, natural selection operates through_______....
The term differential reproduction is used to compare reproduction rates of two groups of individuals of the same generation of a species, each having a different genotype. In Neo-Darwinism (fusion of natural selection and genetic concepts of Mendelism) which is also called as ‘modern synthesis’ theory of evolution. It states that natural selection is the process by which individuals with genetic traits better adapted to their environments survive long and reproduce to produce many offspring, and so transfers the genes for those favourable adaptations to the next generation. The individuals lacking the favourable traits have fewer chances of survival before they can reproduce, thus removing their genetic material from the continuing gene pool.
According to Neo-Darwinism, natural selection operates through_______....
Explanation:
Natural selection, a key mechanism in Neo-Darwinism, operates through differential reproduction. This means that individuals with traits that are better adapted to their environment are more likely to survive and reproduce, passing on their advantageous traits to the next generation. This process leads to the gradual accumulation of beneficial traits within a population over time.
Key Points:
- Natural selection does not involve fighting between organisms or killing weaker organisms. Instead, it is based on the differential reproductive success of individuals with favorable traits.
- Variations in traits within a population provide the raw material for natural selection to act upon. These variations can arise through genetic mutations, genetic recombination, and other processes.
- Individuals with traits that increase their chances of survival and reproduction are more likely to pass on those traits to their offspring, leading to an increase in the frequency of those advantageous traits in the population.
- Over time, natural selection can result in the adaptation of populations to their environments, as individuals with traits that are better suited to their surroundings are more successful in leaving offspring.
- The process of natural selection is a key driver of evolutionary change and is responsible for the diversity of life forms we see on Earth today.
