Explain the inheritance of two genes with example

Dear student
Please find below the solution to the asked query
 
The inheritance of two genes involves transfer of two pairs of contrasting characters from parents to the offspring. 

The inheritance of two genes can be explained by dihybrid Cross.

• In dihybrid cross, we consider two characters. (e.g., seed colour and seed shape)

• Yellow colour and round shape is dominant over green colour and wrinkled shape.

Phenotypic ratio 9:3:3:1

Round yellow 9

Round green 3

Wrinkled yellow 3

Wrinkled green 1
