What Are Genotypes?

Genotype refers to the general term for the entire genetic combination of an individual organism. It reflects the genetic makeup of the organism, the sum of all genes obtained from the parents. The genotype used in genetics often refers to the genotype of a trait. As long as two organisms have different loci, their genotypes are different, so genotype refers to all combinations of all loci of all alleles of an individual. In the hybridization test, it refers specifically to the gene combination that is related to the phenomenon of separation, such as pure high stem pea (DD), hybrid high stem pea (Dd), and so on. Genotypes are generally not directly visible, and need to be inferred from phenotypes through hybridization (testing) tests. ^[1]

The genotype used in genetics often refers to the genotype of a trait. As long as two organisms have different loci, their genotypes are different, so genotype refers to all combinations of all loci of all alleles of an individual. In the hybridization test, it specifically refers to the gene combination that is studied and related to the phenomenon of separation, such as pure high stem pea (DD), hybrid high stem pea (Dd), and so on.

Genotype, also called hereditary type, is

A genotype is also called a genotype, which reflects the genetic makeup of an organism, that is, the sum of all genes obtained from both parents. It is estimated that there are about 30,000 to 50,000 pairs of structural genes in humans. Therefore, the genotype of the entire organism cannot be expressed. The genotype used in genetics often refers to the genotype of a certain trait. For example, the genotype of albinism is CC, which only means that this pair of alleles cannot be produced. Tyrosinase. So the genotype is obtained from the parents and may develop into the genetic basis of a certain trait. Phenotype refers to the sum of all traits of an organism. However, the phenotype of the entire organism cannot be specifically expressed. Therefore, the phenotype actually used often refers to a specific trait of biological development. Such as the body can not produce tyrosinase. A phenotype is a manifestation that an organism's inherited development of a certain trait may become a reality.

The relationship between genotype, performance, and environment The relationship between genotype, performance, and environment can be expressed by the following formula: phenotype = genotype + environment

Taking human eugenics as an example, eugenics are individuals who have excellent phenotypes in terms of intelligence and physical fitness. The phenotype is determined by the genotype (genetic) and the environment. Of course, in the development and performance of different traits, the relative importance of the two is different. People can apply the principle of this relationship to prevent and treat genetic diseases. For example, phenylketonuria is an autosomal recessive disease. It is determined by a pair of recessive pathogenic genes. This environmental condition is an excess of phenylalanine in the body. acid. If phenylalanine is controlled in food and the amount of food containing phenylalanine is the minimum maintenance amount for the human body, the pathogenic genotype will not work, and the phenotype at this time can be normal. Therefore, phenylketonuria can be treated clinically through food therapy. Euclidology is the use of environmental conditions to make good genotypes (genetic basis) fully expressed and improve the phenotypes of bad genotypes.

Almost all human diseases are related to heredity and are affected by the environment. However, different diseases are affected by the two factors of environment and heredity to different degrees. Some diseases are obviously genetically controlled, while others are significantly affected by the environment. effect.
