Which of the following statements regarding model organisms is correct?
a. gregor mendel used pea plant as a model organism for his experiments because it was easy to cultivate and information about the chromosomes was available.
b. caenorhabditis elegans is a multicellular round worm with a short life cycle and the information about the chromosomes is available which allows easy genetic manipulation
c. a model organism should have a fewer offspring's, should have a short generation time and should be responsive to genetic manipulations.
d. according to cdc, 9 out of 10 leading causes of deaths have genetic components involved; therefore a model organism should not be responsive to genetic manipulations and should have longer and stable generation time

After fertilization, which type of cellular division is responsible for the growth and development of a complex, multicellular organism?

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.
