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.

Answer:
The correct option is b) motor output of the spinal cord
Explanation:
Motor neurons, also called afferent neurons, drive impulses from the brain and spinal cord to the receptors (eg, muscles). They are the motor output component of the spinal cord.
The spinal cord is a cord of nerve tissue that runs inside the spine. It conducts the nerve impulses that arrive from the receptors to the brain, and the responses with the motor orders from the brain to the effector organs. Thus, the brain receives the information and can develop an order that modifies the reflex response given by the spinal cord. A spinal nerve has two nerve roots: a motor and a sensory root. The motor root has nerve fibers that carry signals from the spinal cord, to the muscles to stimulate contraction and produce muscle movements, the fibers are efferent as they leave the medulla to the periphery through the anterior roots of the spinal nerves.

Answer:
negative
Explanation:
Lateral-flow pregnancy test
It is a device use to confirm the prsence or the absence of the target analyte , which can be biomakers or the pathogens .
The very common type of lateral flow rapid test is the pregnancy test .
Lateral - flow technology uses colored nano particles , nitrocellulose membrane and antibodies to produce result of pregnancy .
As the sample is added , it flows along the test device passing via the conjugate pad to the nitrocellulose membrane and then to the absorbent pad.
The blue band on the control;l line and no band on the test line , gives a negative test of pregnancy .
That process is called natural selection
