5. A genetics engineer was attempting to cross a tiger and a cheetah. She predicted a phenotypic outcome of the traits she was observing to be in the following ratio 4 stripes only: 2 spots only: 6 both stripes and spots. When the cross was performed and she counted the individuals she found 50 with stripes only, 40 with spots only and 90 with both. According to the Chi-square test, did she get the predicted outcome?

Chemotherapy works by stopping or slowing the growth of cancer cells, which grow and divide quickly. It can also harm healthy cells that divide quickly, such as those that line your mouth and intestines or cause your hair to grow. Damage to healthy cells may cause side effects. Chemotherapy kills cells that are in the process of splitting into 2 new cells. Because cancer cells divide much more often than most normal cells, chemotherapy is much more likely to kill them. Some drugs kill dividing cells by damaging the part of the cell's control centre that makes it divide.
