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

7. What do fruits do for the seed? *
Nikolay [14]
