Explanation:

The small number behind each element symbol designates the number of atoms of each element in a chemical formula. If there is no number, it is assumed there is only one of those elements. A large number designates how many units there are of that compound.

The Punnett square below represents the result of the cross between two tall pea plants.

Mazyrski [523]

Genotypic ratio of offsprings will be homozygous tall : heterozygous tall =1:1.

Tt and Tt if crossed will give 25% progenies as short.

<h3><u>Explanation:</u></h3>

The cross given here is a cross between the two plants, one of which is homozygous tall and other is heterozygous tall plant.

The genotype of the homozygous tall plant = TT.

So, gametes produced from the plant = T.

Genotype of the heterozygous plant = Tt.

So the gametes produced from the heterozygous plant = T and t.

These gametes are written in the Punnett square which gives the offsprings TT, TT, Tt and Tt.

Thus all the offsprings are tall, but the Genotypic ratio is TT:Tt = 1:1.

If Tt and Tt are crossed then 25% of the progenies will be short.
