Detailed explanation-1: -To determine the phenotypic ratio (the number of each different possible phenotype) simply look at each genotype and determine what phenotype would result from it. For example, the genotype GG would result in a yellow seed color. The genotype Gg would also result in a yellow seed color.
Detailed explanation-2: -A person’s genotype is their unique sequence of DNA. More specifically, this term is used to refer to the two alleles a person has inherited for a particular gene. Phenotype is the detectable expression of this genotype – a patient’s clinical presentation.
Detailed explanation-3: -If the paired alleles are the same, the organism’s genotype is said to be homozygous for that trait; if they are different, the organism’s genotype is heterozygous.
Detailed explanation-4: -Different genotypes can produce the same phenotype. Different genotypes can produce the same phenotype.
