Answer:
Step-by-step explanation:
Due to chromosomal duplication and gamete fusion, reproductive differences are inherited from birth. Non-reproductive variants, which can occur before or after birth, are unrelated to variations caused by the fusing of gametes.The primary cause of changes that are not reproductive is a mutation in the DNA sequence.MUTATIONS-A mutation is a sudden, inheritable change to the DNA sequence.X-rays, other high power radiations, or other causes may be to blame for causing mutations.
