A cellular biologist wants to double check a statement that cells spend 90% of their life in
Interphase compared to the other parts of the cell's cycle. The biologist harvests onion root tips
in the laboratory to stain for examination. In this case the null hypothesis is "If cells spend 90%
of their life in Interphase then we will be able to calculate the relative time existing between
Interphase and the other portions of the cell life cycle." 1000 cells were counted under a
microscope. Of the 1000 cells; 875 were counted in Interphase while the remaining 125 cells
were in another portion of the cell life cycle. What are the genotype frequencies for this group of
cells?
