Hereditary diseases are passed from one generation to the next through mutated genes this statement is true.
Further Explanation:
Genetic diseases result from the mutation in complete or in part of gene by changing in the DNA sequence. Genetic diseases mainly develop by a mutation in one gene called monogenic disorder and mutations in more than one gene called multifactorial disorder.
Mutation can occur due to radiations, environmental factor and changing in chromosome position.
Genetic disease mainly of two types:
Hereditary
Non-hereditary
Hereditary diseases are caused due to mutations that are passing from the parents and present in person at the time of birth, like sickle cell anemia. Hereditary disease passes from one generation to the next generation and pass the mutation. Chromosome present in parents passes the mutation to the offspring.
Non–hereditary is caused due to mutations in one gene or more than one gene that occurs due to new mutation in gene. This type of mutation results from change in the position of gene or change in no. or chromosome. They are not inherited from parents.
