In pea plants, tallness (t) is dominant to shortness (t). what is the predicted genotypic ratio of the offspring if a homozygous short plant is crossed with a heterozygous tall plant?

You would have to draw a punnet square to figure this one but here's my

When I was done with the punnet square, I cross the letters between the two plants alleles
For example I cross T with t which makes Tt. Same with the next one, T and t which also makes Tt. Then I cross it with t and you get tt and the next one would also be tt.

So The answer is 50% Tt, and 50% tt

It depends on the surface of the levels. the rougher the surface, the greater is the frictional force. for rougher surfaces, you would need to exert greater force to move the object. the concept is that, you must overcome the frictional force in order to bring the object into motion. this is the reason why we add lubricants to the joints so they could easily move. this answer was on
