Finch species living on the islands exhibit a variety of beak types that favor different foods. Finches that eat seeds and plant parts
have beaks of the shorter, thicker variety while finches that eat insects and other small organisms have thin, pointed beaks.
Drought has hit the Galapagos Islands. Plant species are dying out; seeds and nuts have all but vanished. Of these four finch
species, which is MOST LIKELY to survive under these conditions?
Finch 1
B)
Finch 2
Finch 3
D)
Finch 4

If the birth rate of a population of dolphins is 2.0, the death rate is 0.5, and the population size is 100, what is this dolphin's population growth?

Use this new information to determine the parents’ genotypes (indicated by red arrows). then calculate the probabilities that the second male offspring will have each condition. drag one pink label to each pink target and one blue label to each blue target. then use the white labels to answer questions 1 and 2. labels can be used once, more than once, or not at all.

Considering the yellow and green pea color phenotypes studied by gregor mendel: a. what is the biochemical function of the protein that is specified by the gene responsible for the pea color phenotype? (1 point) b. a null allele of a gene is an allele that does not specify (or encode) any of the biochemical function that the gene normally provides (in other words, either no protein at all or only non-functional protein is produced from it). of the two alleles, y and y, which is more likely to be a null allele? (1 point) c. in terms of the underlying biochemistry, why is the y allele dominant to the y allele? (2 points) d. why are peas that are yy homozygotes green? (1 point) e. the amount of protein produced from a gene is roughly proportional to the number of functional copies of the gene carried by a cell or individual. what do the phenotypes of yy homozygotes, yy heterozygotes, and yy homozygotes tell us about the amount of sgr enzyme needed to produce a yellow color? explain your reasoning.
