Q. Fruitfly is excellent model for genetics because of I. Small life cycle (two week) II. Can be feed on simple synthesis medium III. Single mating produce large number of progeny IV. Clear differentiation of sexes V. Many heredity variation can be seen with low power microscopes Choose the correct option
A) I, II and III
B) III, IV and V
C) I, IV and V
D) All of these
Explanation
Fruitfly is excellent model for genetics because (i) Life cycle is very short (14 days) (ii) Can be feed on simple synthesis medium (iii) Single mating produces large number of progeny (iv) Clear differentiation of sexes (v) Variation can be seen simply by hand lens or simple microscope (vi) They (fruitfly) are easy to handle
