fertilization process.

Expert Solution

fertilization is an important Step in sexual reproduction
fertilization is a fusion of male and female gametes
fertilization brings variation in offspring by mixing gametes from mother and father
Fertilization also is known as generative fertilization, pollination, syngamy, impregnation
During Fertilization haploid male and the female gamete, fuse to give diploid organisms
Four steps in fertilization

preparation of the sperm Here the ejaculated sperm is not ready to fertilize the egg. to fertilize egg sperm undergoes several changes in the female reproductive system called capacitation
Sperm Egg binding Here sperm get attracted toward egg by some chemical signals when sperm reach the egg the Acrososme of sperm burst called Acrosomal reaction by this sperm penetrates the egg coating for fusion
Sperm egg fusion After penetration sperms fuses its pronucleus to the female nucleus now this structure called zygote which is diploid
Activation The fusion of male and female nucleus causes many chemical responses to take place in the zygote, the first response is to prevent polyspermy, then many growth-related responses started to take place and zygote starts mitotic cell division.

Which of the following statements about fertilization is TRUE? Fertilization restores the haploid chromosome number. Fertilization stimulates the initiation of development. Fertilization cannot determine the sex of the offspring. Fertilization permits the formation of gametes with new genetic combinations. In fertilization, a sperm fuses with an ovum to produce an embryo.

In your answer, please thoroughly mention and explain what happens to the egg and the sperm from conception to birth, as well as prenatal hazards and negative effects on the developing embryo. 2.

In Vitro Fertilization Reproductive technologies such as in vitro fertilization (IVF) may allow couples who previously could not conceive to have children. However, the use of these technologies is not publicly funded. This means couples have to cover their own costs and may prevent some couples from having children. You are tasked by the Government of Alberta to determine if IVF should be publicly funded. Evaluate the use of IVF as a reproductive technology. 38. How does IVF work? 39....
