Answer:
Since yellow seeds are dominant, let us assign them the alleles YY
The green seeds will be represented by yy alleles
Therefore for a seed to be green it will have homozygous yy allele however heterozygous Yy seed will be phenotypically yellow
A cross between a homozygous yellow and green will be
(YY × yy)
The resulting offsprings or the F1 generation
will have the genotype. Yy, Yy, Yy, Yy
Phenotypically, all the offsprings will be yellow
