Asexual reproduction

Sexual interactions with same-sex are widespread among animals, but until now the puzzle remains. One of the animals that exhibit this behavior is the Drosophila Melanogaster or fruit flies, in which this paper will be focusing on. Fruit flies have the ability to reproduce rapidly, tendency for males to mate intensely with immature males (Dukas, 2010). Over the past few years, since fruit flies’ genome are simple, researchers made a constant effort in studying the same-sex behavior in Drosophila…

In a new article published in the New York Times, a study was conducted that proves that children who are born from older fathers have a higher risk of getting a mental illness, compared to their siblings. These mental illnesses include schizophrenia, bipolar disorder, and autism (Carey 2014). The study was conducted in Sweden since they keep good track of their medical records. This made it easier for researchers to look at siblings and see if the age of the father had any correlation with…

Fig. 3. Stages of ovarian development in female Q-fly. Stage 1 and 2 represent previtellogenesis development. Stage 3 marks the initiation of vitellogenesis, and Stage 4 indicates late vitellogenesis. Stage 5 ovarian follicles had mature eggs. Stages 1 and 2 are previtellogenic, while stages 3–4 represent the vitellogenic phase. Flies were assigned to stage 5 if the most advanced ovarian follicles had mature eggs. We did not observe stage 6, which is defined by a yellow residual follicular…

Rifkin’s article “Evolution’s Pregnant Pause: Artificial Wombs,” appeared in the Los Angeles Times in 2002, it successfully ask the question is artificial wombs waging a war against natural childbirth and women? This war has worried me because its purpose is to undermine the medical benefits of this technology. Traditionally women give birth, in which women are the principal caregivers of the children. Reading, Rifkin’s article he questions the parental responsibility and the role of women. The…

Abortion is ending a pregnancy before the embryo or fetus can survive outside of the uterus. This is stating that the child cannot withstand life in our world, so how is an abortion considered murder? I think it’s fascinating that people are freaking out about people terminating their pregnancies, but the life forms inside of them still can’t actually live. The child is entirely depending on the mother to live. For the first trimester miscarriage risk is at its highest. This is also the most…

The issue of sex-based abortion is a worldwide issue that most countries are dealing with, and have been dealing with for years. It has been a trend to birth a boy so the family name can carry on or so royal families have an heir to their throne. But some cultures are very strict on the issue and make mothers abort their child if it is not the desired sex. Could this abortion of children go hand-in-hand with gender selection and in vitro fertilization to eliminate the inheritance of disease…

Abortion is one of the most controversial topics in the country today. Many people are blinded by the fact that abortion is murder, and they do not see the effects that abortion may cause. So, what is abortion? Abortion is the cessation of a developing infant in a mother’s body. Fertilization normally takes place only one day after intercourse; this means that as soon as the egg travels into the mother, life is formed. Just within four weeks, the baby has already developed a heartbeat, and a…

I attended the science speaker series on February 27th, when Laurie Mackenzie spoke on the current scientific developments and obstacles relating to the ethics of human reproduction and IVF. She gave a brief overview of how eggs are fertilized, detailing that the lifespan of an egg after ovulation is 12-14 hours, whereas sperm can live for up to 7 days, meaning that the perfect sperm must reach the egg that wants it quite quickly, or else the egg will wither and die, resulting in nothing other…

In the article “Eggs for sale” by M. A. Garcia, the author goes into detail about her journey on aspirating her eggs. She reveals that in the beginning her main focus was on the financial compensation she would receive. Garcia later learned that she would be giving a couple something no one else could. She gave them the gift of life, she allowed them to become parents. Egg donation is an exceedingly controversial topic, many believe that it is unethical to remove the eggs of one female and…

One topic, different approach Writing is a way of communication. People read for various reasons ranging from fun to long-term research. Knowing your target audience and choosing the right language, words, and format for your audience is very crucial to get the desirable outcome out of the audience. This essay will analyze and compare the Sindya N. Bhando's article “Bird Eggs Are Fertilized by More Than One Sperm” published in New York Times, and a scientific jargon “Polyspermy in birds: sperm…
