The balance of nature is a theory that proposes that ecological systems are usually in a stable equilibrium or homeostasis, which is to say that a small change will be corrected by some negative feedback that will bring the parameter back to its original "point of balance" with the rest of the system
Explanation:
"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.
