In a certain plant, tall stems (t) are dominant to short stems (t). a farmer crosses a short-stemmed plant with a heterozygous l
melisa1 [442]

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  

<u />

<u>You can read on to see how this was done:</u>

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

<u>       t        t  </u>

<u>T |  Tt  |   Tt</u>

<u>t  |   tt  |   tt</u>

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

If a mutation occurs such that photosystem ii no longer functions as efficiently as it should, what might be most directly affec
ivolga24 [154]

Out of the following given choices;

a) The amount of oxygen produced

b) The rate of ATP synthesis by ATP synthase in the chloroplast

c) The rate at which NADPH is produced

d) The rate at which the protons are transported into the thylakoid

The answer is; A

The photosystem captures energy from sunlight and uses it to split a water molecule.   After splitting the water molecule (by taking an electron), the protein complex transports the electron to plastoquinone. The splitting of water molecules results in evolving of oxygen molecules. The hydrogen is what is used to reduce carbon dioxide to glucose.
