Beltran · Answer 1

D. multifactorial inheritance

Explanation:

A trait that is regulated by more than one genes and one or more environmental factors and their interactions is said to exhibit multifactorial inheritance. Type 2 diabetes mellitus is also called non-insulin dependent diabetes since blood glucose levels can be regulated by adopting a healthy lifestyle. Obesity, stagnant lifestyle, etc. predispose the risk of type 2 diabetes mellitus among the individuals. The absence of one specific gene as a regulator of the disease and effects of the environment makes type-2 diabetes to exhibit multifactorial inheritance.
