It happens because of Point mutation
Explanation:
A point mutation can be understood as when one nucleotide is added, deleted or changed. Through change in DNA structure a gene can be altered and it is called mutation. Point mutation’s other term is insertion as well as deletion. It mostly involves in substitution.
Rarely, Point mutation is responsible for huge change. Basically, two types of point mutation happen. They are transition or transversion mutations.
The olfactory system is involved in the sense of smell. The receptors of smell are not routed through the thalamus. The signals id directly routed from the olfactory bulb to the olfactory cortex and thalamus is not contacted in between. This is the difference between the taste and smell receptors, although both of their receptors are stimulated from mucus/saliva in the mouth.
