I believe increased blood pressure indicates the presence pf pheochromocytoma. The increased blood pressure could be due to the increased production of catecholamines, indicating a lack of balance in the endocrine.

Mutations are the source of all new alleles. An allele is a variant form of a gene. Variations in alleles lead to variations in organisms. Positive mutations give an organism a better chance of survival. It means that the mutation may be passed on to the offspring. Negative mutations may lead to an early death.<span> Therefore, changes in alleles from one generation to another form the basis of evolution.</span>
