The concept of selective breeding in the mid-1800s discovered the Austrian monk Johann Mendel. He cited two “law” to be forgotten until their rediscovery in the 1900s.
The first law of Mendel said that if the parents are pure strains are crossed, and they differ only by a stroke, for the (two dominant objects his word for genes) and others have two recessive reasons are all first-generation offspring characteristics the dominant factors. For example, the body is a truly engineered layer, and a true blue educate black layer in a small black cat sitting results, black on blue dominates.
The second law states that the crossing of the progeny will be a different in nature. Some of the grandparents are similar in terms of function, and some are similar. Therefore, some of the next generation will have black coats, blue coats, and some have several other layers of paint.
We now know that controlled all the characteristics of a cat or other animals, but by genes located on chromosomes that are. If fertilization occurs, the male sperm unites with the ovum of the woman and child chromosomes are created in pairs. Half of each pair from the father, while the other half from the mother. So, the newly created animals is their genetic programming are given, determine its properties.
