Use the following “evolutionary novelties” to defineeach group: backbone, shell, photosynthetic (produces ownfood), flowers, cones, seeds, heterotrophic (must acquire food),feathers, eukaryotic, and hair. Indicate these novelties onthe tree.Based on this phylogenetic tree, is the group […]

Assume that at a given genetic locus there are two alleles, C and c, and that C is dominant. If the frequency of C in a population is measured and found to be 0.36, what is the predicted frequency of heterozygous individuals (Cc) in the population according to Hardy-Weinberg? If […]
