Flower diameter in sunflowers is a quantitative trait. a plant with 6-cm flowers, from a highly inbred strain, is crossed to a plant with 30-cm flowers, also from a highly inbred strain. the f1 have 18-cm flowers. f1 × f1 crosses yield f2 plants with flowers ranging from 6 to 30 cm in diameter, in approximately 4-cm intervals (6, 10, 14, 18, 22, 26, 30). an 18-cm f1 plant is crossed to a 6-cm plant. what is the probability of an offspring with one additive allele, if all genes that influence this trait are unlinked?

a. 1/3
b. 1/4
c. 1/6
d. 3/8
e. 1/16

Atp is is our little "pocket" of energy. of course, if you have too little, then it means you have too little energy, and you'll pass out. the way to not have enough, is to have no energy sources (glucose, fats, proteins). you can't have too many atp molecules. cycles like the krebs cycle produce it, but if you have too much of any substrate (or too little for that matter), the cycle stops and atp is no longer made (it stops until substrate levels are such that the process can go on). in any case, this is unlikely since atp is constantly hydrolyzed and remade, even while you're asleep. you won't have too much. if you have zero, you are dead or dying.
