Answer 2

Explanation:

1. Fertilization is the fusion of haploid gametes, egg and sperm, to form the diploid zygote.
2. Note though there can be subtle differences in the fertilization process which occurs naturally within the body or through reproductive technologies outside the body, the overall product in both cases is a diplod zygote.
3. In fertilization research, after humans the mouse is the most studied species followed by domestic and farm animals.
4. The process of fertilization involves components of, and signaling between, both sperm (spermatozoa) and egg (oocyte).
5. In addition to in vivo fertilization there are many new in vitro technologies related to human infertility (Assisted Reproductive Technology) and animal production somatic cell nuclear transfer (SCNT) to generate a zygote.
