"two species of salamander inhabit an island. the habitat on each side of the island is different. one side tends to be wet; the other side tends to be dry. researchers want to know if the salamanders will survive equally well on either side of the island. species a lives on the wet side of the island, while species b lives on the dry side of the island. researchers develop two artificial habitats, one that simulates conditions on the wet side and one that simulates conditions on the dry side.
researchers put three salamanders of each species in each of the two different artificial environments. why would other scientists question the validity of the conclusions based on this setup? "

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.
