Which of the following is a valid concern about the impact of biotechnology on biodiversity?
biotechnology will result in depletion of wild populations because high numbers of organisms will be collected for research.
if humans buy only fish produced on aquaculture farms, the fish populations in the wild will decrease.
genetically engineered organisms, being genetically similar, will all be vulnerable to the same diseases.
fish that have been genetically modified will not be able to breed, and species will go extinct.

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.
