This is called cephalization. In mammals, this cephalization occurs primarily in the head...brain, eyes, ears, mouth.
<u>Option A</u>) A nucleotide substitution in the coding region of the lactase gene that interferes with the interaction between lactase and lactose.
<h3>
What mutation causes lactase persistance?</h3>
A mutation in a single nucleotide, in which thymine replaces cytosine, in the region that controls the expression of the lactase gene is what causes the lactase persistence trait.
This mutation first occurred in Hungry, and then it spread out to other regions of Europe, Africa, and Asia.
This mutation allowed humans to digest milk during adulthood.
According to this information, we can assume that the correct option is A). A nucleotide substitution in the coding region of the lactase gene that interferes with the interaction between lactase and lactose.
