1. If two brown mice are bred together, 35 of their 100 offspring are white.
You hypothesize that the parents are heterozygous (Bb x Bb), support your claim

2. A litter of mice was found in the lab, but no one wrote down what their parents were. In this type of mouse, ears
can be curled due to a recessive allele. In the unknown litter, 8 mice have curled ears and 6 mice have normal ears.
You hypothesize that the parents were Bb x bb. Support your claim with a chi square analysis.
