The A gene has two alleles: A₁ and A₂. The A₁ allele improves fitness in hot weather, but it is deleterious when the weather is cold. The A₂ allele performs improves fitness in cold weather and decreases fitness in hot weather. Use the fitness of each diploid genotype in the table below to answer the following questions. Hot Α1 Α1 1.0 Cold 0.4 Α1 Α2 0.8 0.7 Α2Α2 0.5 1.0
