Genetic inheritance begins at the time of conception. Or it can be as complex as how well your liver processes toxins, whether you will be prone to heart disease or breast cancer, and whether you will be color blind.

It can be as simple as eye color, height, or hair color. Genetics is very important in human physiology because all attributes of the human body are affected by a person’s genetic code. Evolution by natural selection is dependent on traits being heritable.
#CO DOMINANT TRAITS CODE#
For all forms of life, continuity of the species depends upon the genetic code being passed from parent to offspring. Genetics is the science of the way traits are passed from parent to offspring. All human cells hold approximately 21,000 different genes. A gene has a certain influence on how the cell works the same gene in many different cells determines a certain physical or biochemical feature of the whole body (e.g., eye color or reproductive functions). Genes control the development and function of all organs and all working systems in the body. This finding contradicted the belief at that time that parental traits were blended in the offspring.Ī gene is made up of short sections of DNA that are contained on a chromosome within the nucleus of a cell. After he crossed peas with contrasting traits and found that the recessive trait resurfaced in the F 2 generation, Mendel deduced that hereditary factors must be inherited as discrete units. Mendel proposed that paired unit factors of heredity were transmitted faithfully from generation to generation by the dissociation and reassociation of paired factors during gametogenesis and fertilization, respectively.

genetics: the branch of biology that deals with the transmission and variation of inherited characteristics, in particular chromosomes and DNA.chromosome: a structure in the cell nucleus that contains DNA, histone protein, and other structural proteins.gene: a unit of heredity the functional units of chromosomes that determine specific characteristics by coding for specific proteins.If the two copies of a gene inherited from each parent are the same, that individual is said to be homozygous for the gene if the two copies inherited from each parent are different, that individual is said to be heterozygous for the gene.A human will inherit 23 chromosomes from its mother and 23 from its father together, these form 23 pairs of chromosomes that direct the inherited characteristics of the individual.Genes are passed from parent to offspring the combination of these genes affects all aspects of the human body, from eye and hair color to how well the liver can process toxins.A gene is a stretch of DNA that helps to control the development and function of all organs and working systems in the body.
