The answer is lateralization of brain function. This is the predisposition for some neural functions or cognitive processes to be more prevailing in one hemisphere than the other. The medial longitudinal fissure divides the human brain into two separate cerebral hemispheres, connected by the corpus callosum.

The answer is A
Breeding of individuals that have genes for a single trait:
MONOHYBRID CROSS.
We call it a monodihybrid cross when we are considering a cross with only one trait or characteristic.
"mono" means one and "hybrid" means that each trait will have two different alleles (for gene A: A or a), one is dominant and the other is recessive.
