Sexual  reproduction Sexual reproduction is a mode of reproduction involving a complex life cycle where the formation of new organisms Occurs by the combination of genetic information from two different individuals of two different types (sexes). The process of sexual reproduction occurs by the formation of gametes with a haploid set of chromosomes. During the process of fertilization, these two gametes combine or fuse to form a cell with a diploid set of chromosomes. Asexual reproduction Asexual reproduction is a mode of reproduction that occurs without the fusion of gametes and doesn’t involve the exchange of genetic information, resulting in offsprings identical to their parents. Asexual reproduction in living beings is characterized by the absence of male and female gametes and the lack of change in the number of chromosomes in the offspring. This results in offsprings that are genetically identical to the parents and each other. These are also called clones.

Cell reproduction  It occurs when, after fertilization, the embryo develops from the zygote by successive cell divisions. Somatic cells make up most of the tissues and organs in your body, including the skin, muscles, lungs, intestines, and hair cells. In humans, the haploid cells produced by meiosis are sperm and eggs. When a sperm and an egg unite at fertilization, their two haploid sets of chromosomes combine to form a complete diploid set - a new genome.

Mitosis and meiosis  Mitosis It occurs when, after fertilization, the embryo develops from the zygote by successive cell divisions. Somatic cells make up most of the tissues and organs in your body, including the skin, muscles, lungs, intestines, and hair cells. Meiosis In humans, the haploid cells produced by meiosis are sperm and eggs.
