After conception comes the process of fertilization, which is the process in which sperm cells must be present in the woman's reproductive tract at the time the egg enters the fallopian tube. This can happen in several ways. If the woman has intercourse with a man during the week preceding ovulation, then he may deposit semen (a fluid containing sperm cells) into the woman's vagina. Some of the sperm can make their way through the cervix (the opening of the uterus, located at the end of the vagina), into the uterus, and on up into the fallopian tubes. There, one of them may meet with the egg as it travels down one of the tubes toward the uterus.
From the eyes to the color of the hair, genetics plays a role in a person’s biological make up and development. Genes can predetermine many different characteristics in human development. Genetics determines simple things as the ultimate height of a person. “The entire genetic code of a human is determined by the unique combination of a mother’s single ovum (egg) and a father’s single sperm” (Mossler, 2011). Therefore every person on the earth is a combination of their biological parents who in turn are a combination of their biological parents and the chain goes on and on.
These systems are very essential to make almost identical new embryo cells to the parents, but each one of them differs from the other. The sperm carries half of the genetic information as chromosomes and transfers it to the embryo when the fertilization occurs and the egg, too. The sperm is produced by the male reproductive system after undergoing several phases or stages. Some of the male reproductive system’s organs are inside the body (internal), and the rest are external. The sperms are formed in the testicles which also release sexual hormones.
Conception and Pregnancy To start this off, conception is the action of conceiving a child, and pregnancy is the period from conception to birth. They both share the same meaning: the process of getting pregnant. Conception happens when a sperm penetrates on one of the female’s eggs. Then, at around day 14 of a 28 day cycle, the egg leaves the ovary, and it is surrounded by a protective layer of cells. The fallopian tube is lined with cilia, which helps move the egg towards the womb.
Almost every person has a wish, a wish to see the magic of seeing there own child given life from there God or Gods and giving the love to their new life that they have made in their own love. But, there is a way for the” 6.7 million women ages 15-44 in the U.S” (www.cdc.gov) to experience the love of that child and to know that their God or Gods gave their child life. That way for women who are infertile to be medically educed pregnancy is called In Vitro Fertilization. That is the reason why there are so many people including myself that support In Vitro Fertilization. In Vitro Fertilization is a perfect way for couples who are infertile to have the feeling of love and blessings of having a child.
Reproductive processes can be categorized in many diffrent ways although the most common is to put them into either asexual reproduction or sexual reproduction. Asexual reproduction is the process by which a single organism gives rise to two or more daughter cells. Most single celled organisms reproduce by the asexual process known as fission, which is commonly called mitosis. Fission (or Mitosis) is the division of one cell into two identical daughter cells. Interphase, the first phase of the cell cycle and also the phase before mitosis, starts as soon as the cell is born.
As humans reproduce sexually, thus Meiosis is a key factor in human reproduction as it occurs during gamete (sperm and egg cell) formation. Mitosis is used for growth and hence when both the sex cells have fused together during fertilisation (two nuclei fusing) they form a zygote which then undergoes the process of Mitosis to form a full organism. Hence, Meiosis (during gamete formation) occurs first in humans followed by Mitosis (for growth of the zygote). The stages of Meiosis and Mitosis are described as follows: ii) Meiosis: This process occurs during sexual reproduction and produces four haploid cells after dividing, resulting in four genetically different cells. There are two nuclear divisions that take place in Meiosis namely, Meiosis-I and Meiosis-II.
It represents nature's solution to the problem of chromosome doubling that would occur, if two diploid cells, i.e. two cells with a double set of chromosomes would fuse. Accordingly does meiosis produce haploid germ cells, with maternal and paternal germ cell fusing at fertilization and thus generating a diploid fusion product, the zygote. Meiosis is made up by two subsequent processes, both of which resemble mitosis. In the first process are the homologous chromosomes separated.
The technique that was made famous by her birth is somatic cell nuclear transfer, in which a cell is placed in a de-nucleated ovum, the two cells fuse and then develop into an embryo” (Science Daily). Clones are the termed referred to when organisms engage in cloning; they are made up of the exact amount of cells and consist of the same genetic material. “Researchers have cloned a wide range of biological materials, including genes, cells, tissues and even entire organisms, such as a sheep” (NHGRI). Cloning all takes control over the same exact DNA schemes for clones. Artificial Copies would be another way to phrase it.
“As most mothers will tell you pregnancy is a roller coaster ride full of laughs, cries, aches, pain and love the likes of which you haven’t experienced never before.” These are the lines from Belly Laughs this book will help you throughout your pregnancy as everything in detail is discussed in this book from day 1 of your pregnancy till you deliver. While the other book Eating for Pregnancy will guide you what to eat that will ensure you deliver a healthy baby. Know the Life that Lives in you As we have come to know to some extent that, Pregnancy is the stage of gestation from the fertilization of an egg through the development of the fetus and ending till birth. In pregnancy, there are multiple gestations and the childbirth usually happens about 38 weeks to 42 weeks after conception which needs complete care according to growing changes in the body. In fact, pregnancy is a great feeling with all these concerns which makes the mother to enjoy full bliss offered by motherhood.
