In pea plants flower color is completely dominant trait with purple flowers being dominant to white flowers. Based on this if you crossed two pure bred flowers, one white and one purple, what would be the expected probability of phenotypes in F2 generation?
A. 75% purple 25% white
B. 25% people 75% white
C. 50% purple 50% white
D. 100% people 0% white

Hello again!

If plants are purebred, then they are homozygous. This means that they have the exact same genes in one pair: for example, AA. If they are both purebred, then the dominant gene will win out every time. The answer for this question, then, would be D. Here is a diagram to help you!

before, trains worked using the steam engine. thus, it uses heat so it is crucial to apply heat balance. the steam engine absorbs energy during the stage of boiling water. so, this is the endothermic reaction. when the steam is used to work the piston, it has to release this energy through running the train. the excess energy is released as an exhaust to the chimney. this is the exothermic process because it releases energy to the surroundings.

a scenario where a cell may be needed to perform a form of endocytosis is when transporting large molecules. a scenario where a cell may be needed to perform a form of exocytosis is when releasing the large molecule from the cell.
