Which of these accomplishes fertilization? which of these accomplishes fertilization? implantation morula formation acrosomal reaction genetic material of sperm and egg combined?

The correct answer is genetic material of sperm and egg combined.
Fertilization is the fusion or joining of the egg and the sperm (haploid gametes), resulting in a fertilized egg, otherwise known as a zygote (diploid). The process of fertilization is very complicated and comprised of many steps, but the key step involves components of and signalling between, both sperm (spermatozoa) and egg (oocyte).

The process that accomplishes fertilization is the combination of the genetic material of the sperm and the egg. When sperms reaches the oocyte, enzymes break down the follicle cells of the corona radiata around the oocyte. Once a path is cleared, sperm undergoes an acrosomal reaction (acrosomal membranes break down and enzymes difest holes in the oocyte membrane). Membrane receptors on an oocyte pull in the head of the first sperm cell to make contact. Fertilization occurs when the genetic material of a sperm combines with that of an oocyte to form a zygote.
