2/8: Warm Up 1 Baby Mice Seif's pet mouse had babies. Five of the babies were black and two were white. The father mouse was black and the mother was white. Seif and his friends wondered why the mice were different colors. These were their ideas: Jerome: Baby mice inherit more traits from their fathers than their mothers. Alexa: The baby mice got half their traits from their father and half from their mother. June: Male traits are stronger than female traits. Seif: Black mice have more traits than white mice. Fiona: The black baby mice are male and the white baby mice are female. Lydia: Parents' traits don't matter-nature decides what something will look like. Billy: Blood type determines what traits babies will have. Which friend do you most agree with and why? Explain your thinking.
