It states that if both the parents inherit the actions of deactivating the form of a faulty gene it can transfer into their offspring.

It gets activated in the body of your child during the fetal and infancy stages. It is a pattern of inheritance where the affected individual possesses two copies of the mutant gene. This disorder only develops when both of the partners have identical defaulty DNA.

This can also happen if one copy of the gene is dominant and one copy is recessive. The chances of getting affected by the genetic mutation can be different, for example, there is a 25% chance that a child may turn out to be normal with no mutation whatsoever or become get affected with two recessive genes, but in this case, there is a 50% chance that the offspring will become a carrier of the disease with no such medical condition.
