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 of the uterus, the traits and phenotypes of the individual are determined.
The principle of segregation for all organisms is as follows:
1. Hereditary traits are determined by specific genes. In the DNA molecule, genes are coded to specify a certain, single characteristic; this includes height, weight, eye color, etc. Any variations of the gene that correlates to the same trait are called alleles.
2. Individuals carry two genes for each trait, one from the mother's egg and one from the father's sperm. One of the genes will be dominant over the other. The dominant allele will mask the other, called the recessive allele. When the father gives a tall allele in regards to the height gene, and the mother gives a short allele, the offspring will be tall. This is because tall is dominant and short is recessive (Gene School, 2010).

In this course, it has been defined as "the study of how biological information is stored, utilized, and passed on from one generation to the next." The cell plays the role of storage, retrieval, and...
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
Nanotechnology attempted to show the potential of this new technology and included the wide range of fields that are connected to the concept of the nanometer scale. These include machining, imaging, metrology or measurement, micromachines, instrumentation and machine tools, scanning probe microscopy, fabrication of components, nanoelectronics, molecular engineering, among others. (Journal Review: Nanotechnology) Another important step in the development of this technology in both a practical and theoretical sense was
The following images show certain disorders that result due to mutation. Children born from the same family members' shows higher similarity index regarding the genetic disorder number inclusive of the Indian community (Cummings, 2010, pg 333). Curbing gene disorders Stoppage of varying types of disorders is possible through learning in consideration of human development the number of genes contained in a single genome, their respective location and the establishment of functions
Behavioral Psychology The main link between the brain and the mind is through the nervous system. It processes information from various regions in the body and transmits it via electrical and chemical signals. The study of the relationship that the brain has on the mind, consciousness and behavior is called behavioral psychology. Decades ago, scientists would use electrodes to stimulate various regions of the brain to understand how it affected the
standing and intense debate as to whether human personality is determined or influenced biologically or psychologically. Those in the pro-biological (or pro-nature) side contend that a person's genes have a stronger or final say about a person's acts and destiny, while those in the psychological (or pro-nurture) side say it is the way the person is/was raised as a child and his peer interaction that determine the personality system
Expression Profiling of a Novel Protein A new transcription unit was discovered while working with transfected murine BAC clones, because a novel spot appeared on a 2-dimensional protein gel. Through a process of expression subcloning from the BAC clone, the transcription unit that generated the novel peptide was located. This finding was back validated by sequencing the protein contained in the 2-D gel piece using N-terminal Edman degradation and mass spectroscopy
