The environment determines which variations are beneficial. Individuals with traits that are well-suited to the environment are more likely to survive and reproduce, while those with less favorable traits may not survive as well.
What role does the environment play in selecting variations?admin2024-10-18T02:12:20+05:30
Variation provides the raw material for natural selection. Individuals with favorable variations are more likely to survive and reproduce, passing those traits to their offspring. Over time, this leads to the accumulation of beneficial traits in a population, driving evolution.

Sexual reproduction involves the mixing of genetic material from two parents, leading to a greater variety of genetic combinations. Asexual reproduction, on the other hand, involves only one parent, so variation is limited to mutations in the DNA.

Variations occur due to mutations, recombination during meiosis, independent assortment of chromosomes, and the random fusion of gametes during fertilization. These processes introduce differences in the genetic material passed from parents to offspring.
