Which of the following is an example of an informal definition? Genetics - that is, the genes you've inherited - may play a role in how your ears react to loud sounds.

The use of genetics is often applied in studies of plant species and improvement. Horticulturalists aim to breed disease-resistant plants by changing their genetic traits. Genetically modified plants are controversial as sources of food crops.

Merriam Webster's Dictionary defines genetics (noun) as "the scientific study of how genes control the characteristics of plants and animals."

Geneticist J. B.S. Haldane makes an interesting point: "I am quite sure that our views on evolution would be very different had biologists studied genetics and natural selection before and not after most of them were convinced that evolution had occurred."

1. read the following excerpt from franklin d. roosevelt's "fireside chat 19":

on the other side of the picture, we must learn also to know that guerilla warfare against the germans in, let us say serbia or norway, us; that a successful russian offensive against the germans us; and that british successes on land or sea in any part of the world strengthen our hands.

remember always that germany and italy, regardless of any formal declaration of war, consider themselves at war with the united states at this moment just as much as they consider themselves at war with britain or russia. and germany puts all the other republics of the americas into the same category of enemies. the people of our sister republics of this hemisphere can be honored by that fact.  

the true goal we seek is far above and beyond the ugly field of battle. when we resort to force, as now we must, we are determined that this force shall be directed toward ultimate good as well as against immediate evil. we americans are not destroyers — we are builders.
