As read in Ch.3, I discovered the impact that science and technology have on creating babies now a day. One specific aspect of new knowledge was the fact that parents are now able to chose the sex of their newborn. There are three different ways to accomplish this. One is by inactivating an X or Y sperm before conception occurs. Second would be by inserting a male or female zygote after in vitro conception. Third would be by aborting XX or XY fetuses. I had no previous knowledge of this and it finally made me realize how far technology has advanced. The fact that you are able to decide and act upon what sex you want your baby to be is a bit terrifying. This process is banned in 36 nations but legal in the United States. I haven't personally…show more content… Since the Y chromosome is passed down to all the male descendants and due to the minimal change from generation to generation, the fact is that males have the Y of a male ancestor who has died thousands of years ago. This aspect of cells and tracing their ancestors is fascinating to me. Not only does it help with searching biological fathers but can help males who are in search of answers coinciding with their ancestors. Another interesting fact was the functions of the placenta with pregnancies. This is the main organ that sustains and develops the baby through the whole pregnancy. The villi, allows for the embryo to have a connection with the mother through the umbilical cord. This cord takes the waste out and brings nutrients from the mother to the embryo. Not only is the placenta viral to life for an embryo but it also allows for early genetic testing. As a parent the cutting of the umbilical cord is seen as a proud moment of the new life that's been…show more content… As I later found out there were different types of twins and each had a distinct process. Dizygotic twins come about two ova ovulated. Each has its own zygote. This is why they don't look exactly like each other and why it's more common to be of different genders. How this relates to my future as a potential mother is that the likelihood of multiple ovulations depends on the woman's genes not the husbands. This was a shock to me but also made me more aware of a situation I could face due to my genes and not my partners. The fact that older women double ovulate more often than younger, meaning the probability of having twins increases through age, allows for me to plan and decide at what age I want to have children. Whether it be to avoid twins or to hope for a higher probability of them, this information is very
