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:
1
1 ∶ 2 ∶ 1 because of linkage of genes
2
9 ∶ 3 ∶ 3 ∶ 1 because of recombination of genes
3
Deviation from 9 ∶ 3 ∶ 3 ∶ 1 ratio because of segregation of genes
4
Deviation from 9 ∶ 3 ∶ 3 ∶ 1 ratio because of linkage of genes
