There are four blood types: A, B, AB, and O. However, there are three alleles that control blood types: IA, IB, and i. Alleles IA and IB are codominant, and the allele “i” is recessive. What are the two genotypes for type A blood? What are the two genotypes for type B blood? What is the one genotype for type AB blood? What is the one genotype for type O blood?

Which of the following is the best definition for the process of photosynthesis? a.) plants digest sugars to make energy. b.) plants use oxygen and glucose to make carbon dioxide. c.) plants use sunlight and carbon dioxide to make sugars. d.) plants use sunlight to make chlorophyll and chloroplasts.

What part of the cell does 9 represent? a. cytoplasm b. lysosome c. ribosome d. centrosome

14) whenever diploid populations are in hardy-weinberg equilibrium at a particular locus a) the allele's frequency should not change from one generation to the next, but its representation in homozygous and heterozygous genotypes may change. b) natural selection, gene flow, and genetic drift are acting equally to change an allele's frequency. c) this means that, at this locus, two alleles are present in equal proportions. d) the population itself is not evolving, but individuals within the population may be evolving.
