The expected phenotypic ratio for a cross between two individuals that are heterozygous for a given trait is 3:1.
<h3>What is Phenotype?</h3>
This is referred to the physical characteristics of an organism such as the size, shape etc.
When two heterozygous traits are crossed:
Rr × Rr ⇒ RR Rr Rr rr

Answer;
-Sensation
Sensation is the activation of receptors in the various sense organs
Explanation;
-Sensation is the activation of sensory receptor cells at the level of the stimulus. Perception is the central processing of sensory stimuli into a meaningful pattern. Perception is dependent on sensation, but not all sensations are perceived.
-Receptors are the cells or structures that detect sensations. A receptor cell is changed directly by a stimulus. A transmembrane protein receptor is a protein in the cell membrane that mediates a physiological change in a neuron, most often through the opening of ion channels or changes in the cell signaling processes.
