Body size in mice (length from nose to base of tail) is controlled in part by genetics. The following data shows the number of mice grouped by lengths:

Length Group Number of Mice
Very small (4-5 cm) 2
Small (5-7 cm) 6
Average (7-10 cm) 15
Large (10-12 cm) 7
Very large (12-13 cm) 1
Based on this data and your knowledge of inheritance patterns, identify the inheritance pattern that this trait follows in mice.
