Answer: The correct option is B.

B. Chromosomes must be copied

Explanation:

This is because, before mitosis occurs the cells must first duplicate or replicate it's DNA during interphase and this is because mitosis is a type of cell division where a parent cell divide into two daughter cells which are genetically identical to the parent cell and carry the exact number of chromosomes of the parent cell.

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
