Pls answer the questions and show the punnett square

Dear student,
Please find below the solution to the asked query

a and b) The genotype of red coloured and axial flowered plant is RRAA and the genotype of white coloured and terminal flowered plant is rraa. 

The cross can be represented as:

Parents               RRAA            X             rraa 

Gametes  of F₁             RA                                 ra

                                                 ↓  

F₁                                     RrAa (All red coloured and axial flowered plants)
 

Selfing                            RrAa           X              RrAa


​Gametes  of F₂                  RA, Ra, rA, ra           RA, Ra, rA, ra
                           
F2

	RA	Ra	rA	ra
RA	RRAA	RRAa	RrAA	RrAa
Ra	RRAa	RRaa	RrAa	Rraa
rA	RrAA	RrAa	rrAA	rrAa
ra	RrAa	Rraa	rrAa	rraa ​​​​​​

Phenotypic ratio: 9:3:3:1

9:  Red coloured and axial flower plant 

3: Red coloured and terminal flower plant

3: White​ coloured and axial flower plant

1: White coloured and terminal flower plant

Genotype ratio : 1:2:1:2:4:2:1:2:1

c) Law of independent Assortment

When two pairs of traits are combined in a hybrid, one pair of character segregates independent of the other pair of character. In a dihybrid cross between two plants having round yellow (RRYY) and wrinkled green seeds (rryy), four types of gametes (RY, Ry, rY, ry) are produced. Each of these segregate independent of each other, each having a frequency of 25% of the total gametes produced.

Both the laws are interlinked. The law of segregation states that the alleles will separate and law of independent assortment tells us that this separation will be independent of each other.
