Question

If someone told you that 9 out of 10 people used their right hand more than their left, would you think that the characteristic was inherited? EXPLAIN why or why not.

Answer 1

Not always.

Step-by-step explanation:

Handedness is a human behavior where multiple factors work on. It is a complex trait. Basically it based on the comfort and skill. One may be comfortable with right hand where others are comfortable with right. Genetic influence is very less in this case, though very little is known about the biological basis. Hand preference tend to be consistent through out the life and begin to develop during the prenatal stage. Recent studies show that multiple genes can be responsible for the handedness.
