Why are some diseases inherited?

Genes are responsible for the transmission of diseases by inheritance. If the gene of one of the parents dominates the gene of the other, the child will receive a disease for which the dominant gene is responsible. Moreover, each gene is a carrier of the code of a particular trait. The father and mother genes form pairs in which one gene is suppressive – dominant, and the other suppressed – recessive. If the mother or father has a pathological gene, then the child will definitely receive it. Moreover, if both parents are carriers of a sick gene, then the risk of a child’s disease is doubled compared to the situation when only one of the parents is a carrier of a sick gene.
If this sick gene is dominant, then the child will be born with a hereditary disease, if recessive, then it will simply be a carrier and pass it on to the next generation. Moreover, if the owner of the suppressed gene finds a person with the same heredity as partners, then in 50% of cases their child will become the owner of the diseased gene. That is why it happens that a sign can manifest itself in 3-5 or more generations.

Remember: The process of learning a person lasts a lifetime. The value of the same knowledge for different people may be different, it is determined by their individual characteristics and needs. Therefore, knowledge is always needed at any age and position.
