Domination

Dominance is a phenomenon found in genetics and biology that refers to the predominance of one allele over another. This occurs when one allele of a gene has a higher frequency than the other allele.

In genetics, dominance is used to describe how genes interact with each other. For example, if a person has two alleles of a gene, one of which is dominant over the other, then he will have a higher level of expression of that gene.

Dominance can be complete or incomplete. If an allele is completely dominant over another allele, it is called complete dominance. In this case, the phenotype will be the same regardless of which allele is present. If an allele is only partially dominant over another allele, it is called incomplete dominance.

In addition, dominance can be multiple or simple. Multiple dominance occurs when alleles interact in such a way that the phenotype depends on their combination. For example, a person may have two alleles of the same gene that are both dominant over the other alleles. In this case, a person may have different phenotypes depending on which alleles are present.

It is important to understand that dominance is not an absolute rule, but rather a statistical phenomenon. Genetic mutations can lead to changes in gene expression, which can lead to a change in phenotype. In addition, epigenetic factors can also influence gene expression and alter dominance.

Thus, dominance is an important concept in genetics and biology that helps to understand how genes interact with each other and how this affects the phenotype. Knowing about dominance can help us better understand how genetic mutations affect our health and development.

Dominance is the inheritance of traits in which the manifestation of one trait in the offspring depends on two parent individuals, and not on one of them. That is, the alleles dominate each other, the dominant allele is suppressed by the recessive allele, and thus only one allele appears phenotypically.

Dominance is widely used in plant growing practice. The genes that cause a particular trait are recessive and dominant. In all living things, according to the laws of nature, different characteristics are determined by a mixture of more than one gene. They can be present in both homozygous,
