question 51 (multiple choice worth 1 points)

one advantage of cloning is

new organisms are often sickly and do not live long lives
through cloning, the diversity of genes would be lost in a species
scientists are able to study how organisms grow and reproduce
cloned animals are less resistant to new diseases

question 52 (multiple choice worth 1 points)

artificial selection is

intentional breeding for certain traits
a process that does not allow a species to reproduce
a natural process
when an organism passes on its traits because it is the strongest

question 53 (multiple choice worth 1 points)

which of the following is not associated with asexual reproduction?

budding
fission
spore formation
fertilization

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.
