Dr.tutus used a twin study to determine the influence of heredity on emotionality.if emotional ality is influenced by heredity, he will found the level of emotional is more similar in? Siblings pairs then in identical twins. B.fraternal twins than in siblings pairs.c.fraternal twins then in identical twins.d. identical twins then in fraternal twins. I am think d.
Sorry about that.
To determine the influence of heredity on emotionality, Dr. Tutus conducted a twin study. Twin studies are a common research method used to investigate the role of genetics in various traits or characteristics.
In this scenario, Dr. Tutus specifically investigated whether emotional stability is influenced by heredity. The question asks about the level of emotional similarity in different pairs of individuals: siblings pairs, fraternal twins, and identical twins.
To answer the question, we need to consider the degree of genetic similarity among these pairs. Identical twins come from a single fertilized egg that splits into two, resulting in two individuals with nearly identical genetic makeup. On the other hand, fraternal twins occur when two separate eggs are fertilized by two separate sperm cells, resulting in siblings with similar but not identical genetic makeup. Siblings share approximately 50% of their genes.
Given that emotional stability is influenced by heredity, we would expect the level of emotional similarity to be higher in pairs of individuals who share more genetic similarity.
Based on this information, the correct answer to the question is:
d. identical twins then in fraternal twins.
Identical twins, who have nearly identical genetic makeup, are more likely to have a higher level of emotional similarity compared to fraternal twins, who have less genetic similarity.
