Solution

The correct option is A
310 & 620

The $F_{2}$ genotypic ratio of Mendel’s monohybrid cross is 1:2:1. Out of the $F_{2}$ progeny 1/4th are homozygous plants with axillary flowers. Homozygous plants with axillary flowers $= 1240 \times \frac{1}{4} = 310$ . Heterozygous plants with axillary flowers $= 1240 \times \frac{1}{2} = 620$ . Thus option A is correct.
