The right option is; D.yes-or-no questions about easily observable characteristics.

A dichotomous key is a tool designed by scientists to help its users to identify a particular type of object and organisms based on physical characteristics. A dichotomous key is divided into two sections and it usually contains specific questions with two choices (yes or no) in each step. When a question is answered, the key guides the user to the next question to ask until the user is able to correctly identify the name of the unknown organism.

The genes for miniature wings (m) and garnet eyes (g) are approximately 8 map units apart on chromosome 1 in Drosophila. Phenoty
Anestetic [448]

The following phenotypic classes reflect offspring that were generated as a result of a crossover event

  • wild type
  • miniature wings
  • garnet eyes

Explanation:

When the miniature wings and garnet eyes links up with the 8 map unit that are present between them. After that the presence of two recombinant classes must complement together and make 8% of total i.e. they contribute 4% each. together the parental classes make up to 92% by contributing 46% one.

This can be understood through a phenotypic ratio calculation, which can be expected from it.

wild type: 4% x 800 = 32

miniature wings: 46% x 800 = 368

garnet eyes: 46% x 800 = 368

miniature wings, garnet eyes: 4% x 800 = 368
