Solution

The correct option is B $37.2 %$
In Drosophila, when white eyed and miniature winged (wwmm) female is crossed with wild type, that is red eyed normal winged (w $^{+}$ w $^{+}$ m $^{+}$ m $^{+}$ ) males, 62.8% of the progeny was of parental types while 37.2% were recombinants. This shows that linkage between genes for white body and miniature wing is loose linkage. Since recombinant occurs along with parental combinations in offsprings, this type of linkage is called as incomplete linkage.
Thus, the correct answer is option B.
