What is Punnett square used for ?

Punnet square is used to know

In a homozygous plant round seeds (R) are dominant over wrinkled seeds (r): Draw a Punnett square to show the gametes and offspring when both the plants have heterozygous round seeds (Rr).

In a homozygous pea plant, axial flowers (A) are dominant over terminal flowers (a). Draw a Punnett square board to show the gametes and offsprings when both the parent plants are heterozygous for axial flowers.

Assertion :- On the basis of Punnett square, the F_(2) generation of dihybrid plant will produce 16 different types of genotypes. Reason:- In F_(1) generatin plant, there are four genotypes of gametes with a frequency of 25% of total gametes produced.

In Mendel's experiments, tall pea plants (T) are dominant over dwarf pea plants (t). Draw a Punnett square board to show the gametes and offspring when both the parents are heterozygous for tallness.

What is the divider used for? Can it be used to draw circles?

Using a Punnett square, work out the distribution of phenotypic features in the first filial generation after a cross between a homozygous female and a heterozygous male for a single locus.

A tall pea plant with yellow seeds (heterozygous for both the traits) is crossed with a dwarf pea plant with green seeds.Using a Punnett square work out the cross to show the phenotypes and the genotypes of F_(1) generation.

A tall pea plant with yellow seeds (heterozygous for both the traits) is crossed with a dwarf pea plant with green seeds.Using a Punnett square work out the cross to show the phenotypes and the genotypes of F_(1) generation.

A pure tall plant (TT) is crossed with a pure dwarf plant (tt). Draw Punnett squares to show F1 generation F2 generation.
