In fruits flies, long wing is dominant to vestigial wing. When heterozygous long-winged flies were crossed with vestigial-winged flies, 192 offsprings were produced. If an exact Mendelian ratio had been obtained, then the number of each phenotype would have been

Options

A. `{:("Long-winged Vestigial-winged"),(" 64 128"):}`
B. `{:("Long-winged Vestigial-winged"),(" 96 96"):}`
C. `{:("Long-winged Vestigial-winged"),(" 128 64"):}`
D. `{:("Long-winged Vestigial-winged"),(" 192 0"):}`

Answer

B

Explanation

A cross between heterozygous long-winged flies and (homozygous) vestigial winged flies represents an example of test cross, in which the exact Mendelian ratio if `1:1` is obtained i.e, 96 long-winged flies and 96 vestigial winged flies.
