Here's a breakdown:
* Sexual reproduction involves the combination of genetic material from two parents.
* Gametes (sperm and egg cells) are produced, each carrying half of the parent's genetic material.
* When a sperm fertilizes an egg, the resulting zygote receives one set of chromosomes from the mother and one set from the father.
* This combination of genetic material leads to genetic variation in the offspring, making them different from both parents.
This process ensures that offspring inherit traits from both parents, contributing to the diversity of life on Earth.
