Ornamental pigeons are pigeons that are specially viewed by humans, so their color and appearance are very important. The general breeding pigeons are not a kind of suit. If they are not controlled, they are allowed to pair freely. They will be in a mess and mixed, eventually destroying the entire pigeon population. In the pigeon world, pedigrees are very important, because good blood pigeons are not easy to come by. Every pigeon owner wants to continue his best pigeon breed and produce more good offspring. To achieve this goal, it must rely on science to achieve. Biology tells us that DNA (DNA) and RNA (ribonucleic acid) are genetic material, and any traits of organisms are not transmitted from the previous generation to the offspring in an existing manner. However, a zygote or fertilized egg can develop. Become a complete individual. It can be seen that all traits of the organism are re-formed during the process of individual development. The transmission from the parent to the offspring is only genetic information, while the substance carrying the genetic information in the cell is called genetic material. The genetic material of most organisms is the DNA that exists in the nucleus of the cell nucleus. The main components of the chromosome are DNA and protein. As a vector of genetic information, it is bound to transfer all genetic information from the line cells to the daughter cells and from the parent to the offspring, so that the previous generation and the next generation can have the same genetic information. Genetic stability, and DNA replication in the cell can ensure the stability of its molecular structure, which is the function of genetic material. The material basis of genetics is the reproduction of cells, chromosomes, and organisms. Cells are the basic structural units of all living organisms (except viruses) in nature. The reproductive ability of an organism is achieved through cell division. Higher animals multiply through the meiosis of cells to produce germ cells. When cells divide, each cell has a certain number of chromosomes in its nucleus. Chromosomes are the major carriers of genetic material. The reason why life can continue from generation to generation is mainly due to the continuous transmission of genetic material to future generations, so that offspring have the same traits as previous generations. In the somatic cell nucleus, the number of chromosomes is even and all are paired. In the nucleus of germ cells, the number of chromosomes is only half of the chromosome number of somatic cells (based on the principle of base pair complementary matching, meiosis refers to the number of chromosomes. Halved cell division). When the eggs are fertilized and bound into conjugates, new individuals are born. In the cells of this new individual, the chromosomes have been restored to pairs and the number of chromosomes has returned to its original number. In this way, the number of chromosomes per organism is kept constant from generation to generation. The carrier of genetic information is intracellular DNA and RNA. Various traits of organisms are expressed in cells through the synthesis of proteins, while protein synthesis is the determination of the molecular structure of DNA through the replication, transcription, and translation of genetic information. The result is that offspring develop similar traits to their parents. Genes are DNA fragments that have genetic effects. The traits of organisms are controlled by genes. Each chromosome contains a DNA molecule. Each DNA molecule has a lot of genes (genes are functional structural units that control biological traits and exist on DNA molecules. ) The inheritance of biological traits is mainly transmitted to offspring through genes on chromosomes. So, DNA is the controller of biological traits, and genes are transferable DNA fragments. These scientific things are invisible to the naked eye, but they have the performance of traits. As the black pigeons that people usually see, there are the genetics of black pigeons, white pigeons have the genetics of white pigeons. The variety of species, their formation actually depends on the genetic, selection, variation of the three major factors, master these basic knowledge, people can control the color and shape of the pigeons.
