Conception, or fertilization, occurs when the male gamete (sperm) fertilizes the female gamete (egg) to form a zygote. The sperm undergoes acrosomal reactions to penetrate the egg's protective layer, allowing the sperm and egg nuclei to fuse together and create a diploid genome.
Conception, also known as fertilization, is the biological process where the male gamete (sperm) fertilizes the female gamete (egg) to form a zygote, the initial stage of a developing organism. This process happens when a sperm cell from the male penetrates an egg cell from the female. In mammals, this usually happens in the oviduct, a part of the female reproductive system. To achieve this, the sperm undergoes a series of biochemical events called the acrosomal reactions, which allow the sperm to penetrate the protective layer of the egg, called the zona pellucida. This leads to the fusion of the sperm and egg plasma membranes, allowing the sperm nucleus to transfer into the ovum. As a result, the sperm and egg haploid genomes condense to form a diploid genome.
