Other enzymes like peptidase and protease are secreted as inactive precursors.

Explanation

For two non-linked genes, the probability of obtaining parental-type offspring in the F2 generation is 6/16,

There are 6 possible combinations of the parental genotypes out of 16 total possible combinations.

Explanation

These receptors are responsible for detecting painful stimuli and conveying the information to the central nervous system.
