What is the difference between bracketed key and indented key?​
____ [38]

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.
