Detailed explanation-1: -The “GG” genotype of rs26802 variant in the ghrelin gene is a potential protective factor against nonalcoholic fatty liver disease.

Detailed explanation-2: -Hence the genotype of the heterozygous yellow seeded plant will be “Yy” and that for green seeded plant will be “yy” (as the recessive allele is expressed only in homozygous conditions).

Detailed explanation-3: -The two alleles of any gene are segregated during the formation of gametes. Thus the green-pod parent (Gg) will produce two kinds of gametes-G and g. The yellow-pod parent (gg) will produce g gametes. As you can see, 1/2 of the offspring are genotype Gg and 1/2 are gg.

Detailed explanation-4: -Now, a pea with t he genes GG will be green is color, gg is yellow, and Gg is green due to the dominant gene, G. The GG, Gg, and gg above are known as genotypes. They denote the specific genes for that trait. The colors, yellow and green, are known as the phenotype, or the physical appearance of that genotype.
