Quizplus · Accepted Answer

The two children differ in temperament, which encompasses emotional intensity and predictability of behaviors such as sleeping patterns. Option A (epigenetic marks) may play a role in development and individual differences, but it is not directly related to the differences between Cathy and Christine. Option B (heritability) refers to the extent to which differences in a trait can be attributed to genetic factors, but it is not clear from the information provided whether this is a significant factor in this case. Option D (extraversion) is not relevant to the description of the infants' temperament and sleeping schedule.
