<span>The total number of genes present in a population is called the gene pool. Hope this helps </span>
Answer:
3:1
Explanation:
Let the allele for tall plant be T; &
The allele for short plant be t
When Mendel crossed true-breeding tall pea plants(i.e TT) with true-breeding short pea plants(I.e tt); all the offspring were tall.
TT × tt
T T
t Tt Tt
t Tt Tt
we can deduce from the punnet square that the F1 offspring are all heterozygous tall plant.
Now, if the first generation (F1) tall plants are allowed to self-pollinate; we have a cross between Tt and Tt
TT × tt
T t
T TT Tt
t Tt tt
We can see phenotypically that we have 3 tall plant(TT,Tt, Tt) and 1 short plant(tt).
Therefore the ratio of phenotypes he expected in the F2 generation is (3:1)
First Gap: The cell is growing in size and is beginning protein synthesis. D<span>uplication is happening.
Synthesis: </span><span>DNA is duplicated so that each chromosome contains two identical copies.
Second Gap: Continues to grow in size and making the amount of protein it needs, also confirming the DNA has no errors in it.
(Also after this the GO phase starts to happen)
