women releases an Ovum from her Ovaries‚ and within a 24 hour period‚ the Ovum must be fertilized by the man’s sperm or else it will die. This normally occurs in the Fallopian Tubes. Once this occurs a Zygote is formed. The Zygote’s cells will begin to multiple and create a Blastocyst. The Zygote must now make its journey through the Fallopian Tubes in order to attach itself to the women’s Uterus where it begins to grow remarkable fast. This is normally a 2 week process. Once attached to the body

division (meiosis) • Zygote: when sperm and ovum unite at conception‚ will have 46 chromosomes • Autosomes: 22 of the 23 pairs of chromosomes are matching pairs • Sex Chromosomes: the twenty-third pair; females: XX males: X; Y is short and carries little genetic material‚ X is a relatively large chromosome • Fraternal/Dizygotic twins: most common type of multiple birth‚ resulting from the release and fertilization of two ova • Identical/Monozygotic twins: a zygote that has started to duplicate

Ethology & Human development The study of evolutionary behaviors Bowlby Infants have a number of behaviors that are biologically programmed that serve the purpose of bringing adults close to them and caring for them – infants cry as a distress signal Infants physical appearance also develops from natural selection Sensitive periods: period of time when it is most optimal to see a behavior‚ or develop a relationship. He argued that the first 3 years are a sensitive period for the development

GENE THERAPY Gene therapy is based on the concept that genetic disorders and acquired diseases can be treated by replacing abnormal or absent genes or by modifying their functions. Inherited disorders such as cystic fibrosis and haemophilia‚ as well as catastrophic diseases such as cancer and AIDS‚ are prospective candidates for gene therapy. Although cures for these ailments would be welcome‚ some medical researchers suggest that the range of diseases that can be treated with gene therapy may be

The Human Genome Project The Human Genome Project is a worldwide research effort with the goal of analyzing the structure of human DNA and determining the location of the estimated 100‚000 human genes. The DNA of a set of model organisms will be studied to provide the information necessary for understanding the functioning of the human genome. The information gathered by the human genome project is expected to be the source book for biomedical science in the twenty-first century and will be of

Before Life As We know it Introduction Individuals tend to question how life came about and how we ended up as the Homo sapiens that we are male or female respectively. Little do they know there are several processes‚ which take place before we eventually become the person we are. “It appears to be reasonably established that the functional gametes of many organisms are derived from primordial germ cells already present in early embryogenesis”(Clement 3). Before gametogenesis‚ the primordial
Premium Meiosis
Introduction For a zygote to contain a diploid complement of chromosomes‚ the gametes‚ which fuse to form this zygote must contain half the number of chromosomes. This reduction of chromosome number occurs in two distinct sequential phases of meiosis‚ termed meiosis I and meiosis II. Both divisional sequences have sub-stages such as‚ prophase (I‚ II)‚ prometaphase (I‚ II)‚ metaphase (I‚ II)‚ anaphase (I‚ II)‚ and telophase (I‚ II) that is continued by cytokinesis (I‚ II)‚ which is not part of meiosis

MENDEL`S PRINCIPLES OF GENETICS 1.0 INTRODUCTION: 1.1 BACKGROUND Gregor Mendel‚ who is now considered as founder of classical genetics‚ ( Elrod S. & Stansfield w‚2010)‚ conducted a series of experiments using garden pea plants‚ his aim was to find a way of explaining to his fellow scientists who believed the blending theory which had been proposed earlier by Wiseman‚ that heredity involved the interaction of discrete separable factors (now known as genes) After a statistical analysis of the
