Q. Show the process of Construction of Keys?

Keys are constructed using contrasting characters. The possible names in the key are divided into smaller and smaller groups. Each time a choice is made, one or more taxa are eliminated. Statements in the key are based on the characters of the plants. Such as herbaceous versus woody: If herbaceous eliminate woody plants ii) zygomorphic flowers versus actinomorphic. If zygomorphic eliminate actinomorphic flowers.

Each time a choice is made, the number of taxa is reduced by the use of contrasting characters. dare constructed in a different. manner while based on the same matter. A good key is strictly dichotomous, not having more than two alternatives at any point.
