Question

Given below is a dihybrid cross performed on Drosophila.

Which of the following conclusions can be drawn on the basis of this cross? When yellow bodied (y), white-eyed (w) Drosophila females were hybridized with brown bodied (y+), red-eyed males (w+) and F1 progenies were intercrossed, F2 generation would have shown the following ratio:

पर्याय

• 1:2:1 because of linkage of genes

• 9:3:3:1 because of recombination of genes

• Deviation from 9:3:3:1 ratio because of segregation of genes

• Deviation from 9:3:3:1 ratio because of linkage of genes

Answer 1

Deviation from 9:3:3:1 ratio because of linkage of genes
