1)Control Group - Group that does not receives the treatment.
2)Experimental Group - Group that receives the treatment.
3)Constant - The variable you keep the same.
4)Independent Variable - The variable you control.
5)Dependent Variable - It depends on the independent variable.

Example:
You want to know how much taller plants will grow with fertilizer. You do an experiment. Flower A receives fertilizer but flower B does not. Both flowers receive the same amount of water and sunlight. The control group would be flower B, the constants would sunlight and water, the independent variable would be the fertilizer., the dependent variable would be the plant's height, and the experimental group would be flower A.

In pea plants, tallness (T) is dominant to shortness (t). What is the predicted genotypic ratio of the offspring if a homozygous
tino4ka555 [31]
First, to answer this question, you need to draw a Punnett square. So you put the homozygous short alleles (tt) on top of the square, and the heterozygous tall alleles (Tt) on the left side of the square (or vice versa, it doesn't really matter).

When you create the Punnett Square, you then perform the cross between the two plants' alleles. I cross t with T and that gives me Tt. Same with the next one, t and T becomes Tt. Then, I cross t with t and that gives me tt. Same with the next one, t and t becomes tt.

So, the answer here would then be c. 50 percent Tt, 50 percent tt. You might say, well, couldn't answer d also work? Answer d could only work if the question was asking for the phenotypic ratio of the offspring. Then you could say 50% tall, 50% short. But the question asks for the genotypic ratio, so it would instead be c. 50 percent Tt, 50 percent tt.

Hope this helps!
