It’s asking you to start yourself off at one of the various stages that water goes through. You are to pretend to be a water molecule at one of those stages (your choice) and from there go through the whole cycle back to where you started. Basically it wants you to show the water cycle.

There are different versions of the water cycle depending on how complex they want it. The basic water cycle is collection, evaporation, condensation, precipitation (Note: do not put this as this answer if it’s a higher level course talking about other aspects of the cycle like run-off and transpiration).

In a certain plant, tall stems (t) are dominant to short stems (t). a farmer crosses a short-stemmed plant with a heterozygous l

The answers would be:

Genotype Phenotype

Tt Tall stemmed

tt Short stemmed

Genotypic ratio : 2:2 or 1:1

Phenotypic ratio: 2:2 or 1:1

You can read on to see how this was done:

Tall stems (T) are dominant to short stems (t).

First figure out the genotypes of the parents. We have a short-stemmed plant and a heterozygous long-stemmed plant cross.

For short stem to occur, you need 2 pairs of short alleles. So the first parent would have a genotype of tt.

Heterozygous long-stemmed means that the parent has one of each allele. So the genotype of the second parent would be, Tt.

Now we can make our Punnett Square.

tt x Tt

t t

T | Tt | Tt

t | tt | tt

Let's list down the genotypes and phenotypic results.

Genotype no. Phenotype

Tt 2 Tall stemmed

tt 2 Short stemmed

So from that we can answer the other questions:

Genotypic ratio : 2:2 or 1:1

Phenotypic ratio: 2:2 or 1:1
