Reproduction Male sperm fuses with female egg. If tdf (a gene) is present‚ then the embryo develops testes and produces testosterone. Female Reproductive system • Female baby develops if tdf is not present. • Tdf – a gene located on Y chromosome; if girl‚ then two X chromosomes‚ hence no Tdf. • Female hormones: progesterone and estrogen ( both secreted by mother’s ovaries and placenta which allow female genetilia to develop.

Preimplantation Genetic Diagnosis (PGD) involves the testing of numerous embryos‚ not just one. After all of the embryos have gone through screening and received a diagnosis‚ the parents choose one embryo to implant and the others are usually discarded. PGD is a process of selection‚ not prevention. In other words‚ PGD is not the prevention of a single embryo from having a disability; it is the selection of an embryo without one. In this paper I will argue that PGD is morally wrong. Many families

of mitotic cell divisions without cell growth between division cycles. There is close to no cell growth because during cleavage‚ the embryonic cells undergo the S and M phases of the cell cycle but practically avoid the G1 and G2 phases. Thus‚ the embryo does not increase in cytoplasmic material or enlarge but merely partitions its zygote into smaller blastomeres. The first five to seven divisions produce a

Question: Is IVF worth the risks and possible side effects for the mother and child? The process of conception is open to a myriad of complications‚ starting from fertilization. If an individual‚ male or female‚ is infertile‚ they are biologically unable to contribute to the conception of a child. According to McArthur ’s ’Infertility statistics ’ (2007) one in eight couples are infertile.

There are basic principles that address the issue of fairness‚ honesty‚ and respect for fellow human beings. Because of some cultural values and religious beliefs‚ there is a big controversy whether this type of study is ethical or not. Due to a human embryo having to be destroyed in order to obtain an embryonic stem cell‚ some people believe this is a disregard for human life. I disagree with this statement because the stem cells are derived from eggs that have been fertilized in-vitro (within a fertility
