It is a monohybrid cross. Monohybrid cross produces progeny of F2 generation in ratio 3:1 where 1 is the ratio of recessive progeny. Here in, the number of recessive white-eyed individuals can be found by:
Total number according to ratio = 3+1 = 4.
Total number of individuals produced actually = 12
Number of white-eyed individuals = 14×12=3
