Alleles Dominant

The dominance of alleles is one of the most important mechanisms of heredity, which determines the properties of the organism and its response to the environment. In genetics, the dominance of an allele means that it always appears in heterozygous and homozygous states. However, in some cases, a dominant allele may also prevent the expression of other genes in heterozygous organisms. This phenomenon is called “dominant alleles.”

Dominant alleles can appear in different genes and lead to different phenotypic effects. For example, some alleles can determine the color of skin, hair, eyes, etc., while others can affect height, weight, health, etc. If the dominant gene has adverse consequences for the organism, then the heterozygous state can lead to decreased viability and reproductive ability.

However, in some situations, dominant alleles can also have beneficial effects on the body. For example, a dominant allele that determines disease resistance can increase an organism's survival rate and protect it from infections.

In general, dominant alleles play an important role in determining the body's properties and its response to the environment, and understanding them can help develop more effective treatments and prevention of diseases.

Dominant alleles are groups of genes that are expressed in all cells of the body. They allow the genetic characteristics of organisms to be identified. While other genes may vary due to hereditary factors, the dominant alleles remain the same and unchanged.

In addition, there are recessive alleles - this is a group of genes that appear only in heterozygous and very rarely in homozygous states. For homozygosity dominance to work, there must be a complete match between the 2 recessive alleles. If the allele is one recessive and the other dominant, then
