Which type of reproduction produces variation in the offspring?

Sexual reproduction is the type of reproduction that produces variation in the offspring. Here are the steps explaining why:

1. Sexual reproduction involves the fusion of male and female gametes (sex cells) in a process known as fertilization. Each parent contributes half of the genetic material for the new organism.

2. The male and female gametes each carry different genetic information because they are produced through a process called meiosis. During meiosis, the number of chromosomes is halved and the chromosomes can exchange genetic material. This results in gametes that are genetically unique.

3. When a male and female gamete fuse during fertilization, the resulting offspring has a combination of genetic material from both parents. This genetic mix produces variation in the offspring.

4. Over time, this variation can lead to evolution as certain traits may provide an advantage in a particular environment, making those with the trait more likely to survive and reproduce. This is known as natural selection.

5. Therefore, sexual reproduction is the type of reproduction that produces variation in the offspring.
