Liam and lochlan are identical twins. liam was raised by his father and mother, and lochlan was accidentally placed with another family after the confusion of an earthquake that hit their town. at the age of 13, both boys "ran into each other" at a soccer game and noticed how they appeared to look exactly alike. after proving they were twins by genetic testing, the families discussed some of the differences between the boys. liam is very athletic and intelligent and excels in basketball but does not take school seriously and has f's in all subjects. lochlan is also athletic and intelligent, and excels in baseball and makes straight a's as a result of his strict home life and study routine. although they are identical twins, what do you think accounts for the differences in their academic performance based on the research?
