Answer:
The correct answer is option C. "pleiotropy".
Explanation:
Pleiotropy is a characteristic that defines a gene that is responsible for the development of multiple traits, which often seem to be unrelated. Sickle-cell disease is an example of a disease caused by the mutation of a pleiotropic gene, resulting in the person developing red levels, blood clots, and strokes. Other example is the disease phenylketonuria, at which the affected person suffers from a mental disorder and reduced hair and skin pigmentation by a single mutation in a single gene on chromosome 12.

Answer:
<em>Bracketed and indented keys are two dichotomous/or branching keys with an ordered, numbered couplet, and spatially differentiated respectively.</em>
Explanation:
Dichotomous keys are used in the identification and classification of taxa.
Bracketed keys, or parallel keys, are easy to understand- for efficiency, these keep the first two entries of every couplet or pair being compared. It also makes use of a numbering system in the couplet choices for easy tracking.
Indented keys maintain an equal distance from the margin on the left of the pages. Successive couplets are indented til the taxon is identified.
