In sexual reproduction, offspring are genetically different from their parents. This is because of the crossing over in meiosis.
Further Explanation:
All the living things reproduce through a process referred to as reproduction. The process of reproduction can occur in two types:
The asexual reproduction is a major type of reproduction in single-cell organisms like bacteria, Protista and archaea. Some fungi and plants also reproduce sexually. In this process, the offspring is produced from one parent and also pass the genetic information from one parent. The offspring is exact copy of parent because there is no genetic variation.
Sexual reproduction is the major method of reproduction in a variety of microscopic organisms. It almost includes all the plants and animals. The main process in sexual reproduction is:
Fertilization is a process of the fusion of gametes which are sperm and egg results in the diploid zygote. In meiosis ploidy level of germ cell get halved. Meiosis involves crossing over in between the non-sister chromatid of the homologous chromosome thus leads to genetic variation. So, the parents and offspring are genetically variable from one another.
