First, you need to do the multiplacation that's inside the perenthises.
Second, you will need to divide the two answers which will give you that first box.
"Identical twins are more similar on the trait than fraternal twins" would lead to the conclusion that genetic factors are important in the development of this trait.
<u>Option: C</u>
<u>Explanation:</u>
Research performed on identical or fraternal twins are twin investigations. We seek to expose the significance for characteristics, phenotypes and diseases of environmental and genetic factors. Twin work is considered a key instrument in the domains of behavioral genetics and material, from biology to psychology.
Fraternal or dizygous twins each share around 50 % of their DNA, just like any other parent. Since the twins are born into the same family they share other factors of their surroundings. The existence of a given genetic or phenotypic trait in just one component of a pair of twins called discordance offers a valuable insight into influence on such a trait on climate.
