A field experiment is conducted to test for a heterozygote advantage in the survival of a mustard plant. When heterozygotes for
the Alocus are first crossed, the yield is 200 AA, 400 Aa, and 200 aa( i.e., a ratio of 1:2:1). In trial 1, 35 AA, 44 Aa, and 23 aaplants survive. In trial 2, 25 AA, 68 Aa, and 21 aaplants survive. Based on these results, which of the following statements is true? a. Only trial 1 shows heterozygote advantage.
b. Only trial 2 shows heterozygote advantage.
c. Both trials 1 and 2 show heterozygote advantage.
d. Neither trial shows heterozygote advantage.
e. Insufficient information is given to answer the question
