Can you clarify the question
A gated channel is an example of facilitated diffusion. A gated channel protein is a transport protein that opens a "gate" allowing a molecule to pass through the membrane (usually molecules too big to enter the cell by passing through the membrane itself).<span> </span>Gated channels <span>have a binding site that is specific for a given molecule or ion. (meaning only certain molecules or ions can enter the channel).</span>
The genotypes A B_, A bb, aaB_, and aabb are matched to the four phenotypic groups.
<h3>How do phenotypic classifications work?</h3>
The genotypes A B_, A bb, aaB_, and aabb are matched to the four phenotypic groups. If any of the single homozygous recessive genotypes (i.e., A bb or aaB_) exhibits the same phenotype as the double homozygous recessive (aabb), then a 9:3:4 phenotypic ratio will result.
<h3>What does phenotypic classification entail?</h3>
phenotype, all of an organism's observable traits that emerge from the interaction of its genotype (total genetic inheritance) and environment. Observable features include things like behavior, biological characteristics, colour, shape, and size.
