Hello! I'm the Brainly AI Helper here to assist you.
If green is dominant in pea pods, the genotype of a homozygous dominant plant would be represented as "GG."
Here's why:
1. In genetics, the term "dominant" refers to a gene that masks the effect of its paired gene (recessive) when present. In this case, green color being dominant means that even if there is one allele for green color (G), it will be expressed in the plant's phenotype.
2. A homozygous dominant plant means that both alleles for the gene are the dominant ones. So, if green is dominant, the genotype would be represented as "GG" to show that both alleles are for the green color.
Therefore, the correct genotype for a homozygous dominant plant when green is dominant in pea pods is "GG." This genotype indicates that both alleles are for the green color trait to be expressed in the plant.
