Genetic Growth Factors Practice Test

A class studied two inherited lines of mice (Line 1 and Line 2). Newborn mice were raised in the same room with the same temperature, same type of food, and the same feeding schedule. At 6 weeks, the average mass was recorded.

Which prediction about growth is supported by the evidence that genetics can influence growth?

Two varieties of corn (Variety T and Variety U) are planted in the same field row-by-row so they get the same sunlight, soil, water, and fertilizer. The varieties come from seed lines that have produced different average plant heights for many generations. At maturity, Variety T averages 210 cm and Variety U averages 170 cm. Which prediction about growth is supported by the evidence?

Statement: Genetics can influence growth when inherited traits differ and conditions are the same.
