Chromosomes are more likely to be passed on from generation to generation, because it is known that about 40% of all spontaneous miscarriages are associated with chromosomal changes, and 6% of stillborn children have abnormalities in the number and structure of chromosomes; 6 out of 1000 newborns have chromosomal abnormalities. And in gene diseases, the inheritance and degree of manifestation in the offspring depends on the severity of the disease in the parents, since their severity is due to a defect in several genes. For example, if both parents suffer from hypertension, then the risk of developing a more severe disease in children increases, as well as the likelihood of inheriting pathological genes. Of great importance is the degree of kinship of this individual with an affected family member. The farther they are related, the less likely the manifestation of the disease.
