Life Science Assessment Probe Baby Mice Seif’s pet mouse had actually babies. Five of the babies were black and 2 were white. The father mouse was black. The mom mouse was white. Seif and also his friends wondered why the mice were different colors. These were their ideas: Jerome:Baby mice inherit even more traits (genes) from their fathers than their mothers. Alexa:The baby mice gained half their traits (genes) from their father and fifty percent from their mom. June:Male traits (genes) are stronger than female genes. Seif:Babsence mice have more traits (genes) than white mice. Fiona:The black baby mice are more than likely male and the white baby mice are most likely male and also the white baby mice are probably female. Lydia:Parent’s traits (genes) favor hair color don’t issue – nature decides what something will certainly look prefer. Billy:Blood kind determines what traits (genes) babies will have.
