Genotype: 1:2:1
Phenotype: 3:1
Step-by-step explanation:
An identity specific to that of an allele of a gene is considered as the genotype of that gene and the phenotype of the gene is the expression of the genotype. In Mendel's model, the ratio between the genotype and the phenotype of the seed colors in the generation of F1 is expressed.
The possible genotypes in this generation are heterozygous and identical seeds of green color and phenotypes are of yellow color. The ratio of the genotype and phenotype is 1:2:1 and 3:1 respectively
