With recessive genes (in which both mother and father have to contribute a 'positive' set of the same genes) are designed to work in precisely the same way that hemophilia does: One out of four offspring (on average) will have the condition, two will be carriers, and one will be neither sick nor a carrier.
Klinefelter's syndrome, on the other hand, arises from a mechanical mistake that occurs on the genetic level during the process of the way in which egg and sperm come together to create a genetically whole zygote/fetus/baby. Under normal genetic conditions, an egg brings half of the needed genetic material to an individual. This female contribution is referred to as the X chromosome. Sperm, which also contribute half of an individual's genetic material, can be either X or Y in terms of chromosomal type. An X sperm combines with the X chromosome of an egg to produce a girl; a Y sperm chromosome combines with the X chromosome of an egg to produce a boy (Klinefelter syndrome, 2007).
This process works very smoothly most of the time. However, sometime, when sperm are being produced, something breaks down in the process and instead of a sperm being formed as either an X chromosome sperm or a Y chromosome sperm, the sperm's own chromosome does not divide properly and the sperm has both an X and a Y chromosome. When this happens, a boy is born who has Klinefelter's syndrome, which is the genetic expression or consequence of a boy who has not the usual XY genetic structure of males but a structure of XXY, which can in very general terms be seen as something of a genetic combination of male and female genetic structures (Samango-Sprouse, 2010).
This mixture at the genetic level of male and female structures is reflected in the physical condition of males with Klinefelter's syndrome. While they are externally male (that is, they have a penis and testicles)...
Genetics and Development Genetics is a scientific discipline that deals with how individuals inherit their physical and behavioral attributes. Generally, genetics is a branch of biology that deals with the science of heredity, genes, and differences in living organisms. It's the process with which a child inherits traits from his/her parents and the molecular organization and function of genes. The question of what determines the development of a child has been
Genetics and Development: As a discipline of biology, genetics is basically considered as the science of genes, inheritance, and differences in living organisms. Since genes are common characteristics in living organisms, genetics is used in the study of all living systems including plants, humans, domestic animals, bacteria, and viruses. Generally, this biological discipline focuses on the molecular structure and operation of genes whose behaviors are in the context of organisms or
Hence, genetic factors underlie the stability or continuity of psychological traits. Gene Development Mutations play a vital role in genetics, although they cause different disorders living things. Sometimes heredity causes disorders that affect the normal genetic development. Genetic processes control how humans develop from a single cell to adult human beings. Genes control the nervous system cells, and re-growth of skin and hair cells. Genes make humans dynamic organisms capable of

The information is then transcribed into the traits and phenotypes of the offspring depending on the dominance and recessive alleles within the gene (Berg, Tymoczko, & Stryer, n.d). The egg is fertilized by the sperm from the mother and their nuclei fuses together to form a zygote. The zygote contains 23 chromosomes from the mother and 23 from the father. From this combination of genes and the environmental conditions
