The dependent variable is the variable which is under study and being tested.
For example, to check the difference in photosynthesis rate by light, the amount of light will be the independent variable and the rate of photosynthesis will be the dependent variable.
Coat color in one breed of mice is controlled by incompletely dominant alleles so that yellow and white are homozygous, while cream is heterozygous. Thecross of two cream individuals will produce <span><u>equal numbers of white and yellow mice, with twice as many creams as the other two colors.</u></span>
