in steps of fertilization which one is comes first sperm penetration or fusion of gametes
1 answer
In the process of fertilization, the fusion of gametes occurs before sperm penetration. The fusion of gametes refers to the fusion of the egg and sperm nuclei, also known as the process of syngamy. This fusion forms a single cell called a zygote. Following the fusion of gametes, the sperm penetrates the egg cell to release its genetic material, allowing for fertilization to be complete.
