Jennifer Sozio Section Instructor: Ms. Colleen Farrell Ethics: PHI-104-51-8 26 June 2012 THE MORAL ISSUE OF ABORTION The moral question on both sides of the abortion argument is when a fetus achieves personhood and is awarded moral status thus granting it rights. Does the fetus have a right to life at the use of the mother or does the mother ’s choice for autonomy over her body take precedence over the fetus? How do we begin to answer this highly debated question and what conclusions can

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. It has an unusually long prophase that is subdivided into different stages They are followed by metaphase

Abortion‚ a medical practice that results in termination of a human pregnancy‚ dates back to ancient Egypt and is recorded in the Ebers Papyrus‚ a medical text from the time of 1550 BCE (“When Did Abortion…”‚ par. 2). Abortion is a hot topic that is currently sweeping the US and has been for many years now. There are two stances citizens tend to take on the issue of abortion: pro-choice and pro-life. Many people do not advocate strongly for either; they lie somewhere in the middle gray area. Both

the gametophyte displaying its hermaphrodite form‚ sexual maturity allows cross-fertilization to occur between the sperm from antheridium and the egg from archegonium. After one sperm fertilizes the egg‚ a zygote forms‚ thus forming a diploid cell (Hoshizaki 2001). The formation of the zygote exemplifies sporophytes’ alternation of generations via the diploid cell completing mitosis and meiosis yet still retaining a full set of genetic material. In other words‚ alternation of generation refers to
