In peanut, a plant may be of the forms "bush" or runner". 2 different strains of peanut, V4 and G2, in which the "bush" phenotype occurred, were crossed with the following results: V4 bush x V4 bush = all bush  G2 bush x G2 bush = all bush   The 2 breeding strains of peanut bush were crossed in the following way: V4 bush x G2 bush = F1 runner F1 x F1 = 9 runner: 7 bush   What are the genotypes of the parent and offspring? what is the genetic basis of the inheritance pattern of runner and bush in the F2 peanut?

In peanut, a plant may be of the forms "bush" or runner". 2 different strains of peanut, V4 and G2, in which the "bush" phenotype occurred, were crossed with the following results:

V4 bush x V4 bush = all bush 

G2 bush x G2 bush = all bush

 

The 2 breeding strains of peanut bush were crossed in the following way:

V4 bush x G2 bush = F1 runner

F1 x F1 = 9 runner: 7 bush

 

What are the genotypes of the parent and offspring? what is the genetic basis of the inheritance pattern of runner and bush in the F2 peanut?
