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
The Moon appears to change shape because we see different amounts of the lit part as the Moon orbits Earth. From Earth's perspective, we see varying amounts of the illuminated part of the Moon.
