selfed and total 2000 seeds were collected. What
is the total number of seeds heterozygous for both
the traits?
(1) 250
121 500

Answer 1

500 is the right answer.

By selfing F1 generation, Out of 16 possibilities shown in 2nd attachment the rounded ones are heterozygous for both traits.

ie;- 4 out of 16 possibilities. ie:- 0.25 of total.

= 0.25 * 2000 = 500
