Q1. True-breeding tall red-flowered plants are crossed with dwarf white-flowered plants. The resulting F} generation consists of all tall pink-flowered plants. Assume that height and flower colour are each determined by a single gene locus on different chromosomes, predict the results of an F} cross of dihybrid plants. Select appropriate symbols for the alleles of the height and flower colour genes. List phenotypes and predicted ratios for the F2 generation.
Q2. What adoptions increase surface area in animal systems and how do the increased surface area get better the function of that system?
