Low birth weight can have many effects on development. This study observes the relationship between a mouse’s birth weight and its motor development. Forty mouse pups from various litters, aged 7 to 14 days old, were led through a series of physical challenges to determine how advanced their development was in relation to their age. Hypothesizing that there would be a positive correlation between pup weight and development of motor skills, we found a significant relationship between a mouse pup’s weight and its development. By testing pups’ motor development skills using various tests, we were able to conclude that mice with a heavier weight develop more efficiently than those who are below average. Understanding the early development of laboratory mice may help us understand other mammals, including human beings.
