AP BIOLOGY

Detailed explanation-1: -Since the Y (yellow) allele is dominant over the G (green) allele for pea plants, 100% of the YG offspring will have a yellow phenotype, as Mendel observed in his breeding experiments.

Detailed explanation-2: -The physical expression of a genotype that can be visually observed is known as a Phenotype. a pea plant has a yellow pod phenotype, its genotype may either be GG or Gg. phenotype (green pods), then the individual parent having the dominant phenotype must be heterozygous.

Detailed explanation-3: -The phenotype, or observable trait of this pea, is therefore green. In total, there are three different genotypes possible for the pod color characteristic. Here’s the one we’ve just discussed. The pea could be homozygous for the dominant green pod trait. Homozygous means they have two alleles that are the same.

Detailed explanation-4: -Answer and Explanation: The cross between a green pea plant (Gg) and a yellow pea plant (gg) is shown below: From the cross, we can see that the possible genotypes are green and yellow. 50% of the offspring will have a Gg phenotype and 50% will have gg phenotype.

Detailed explanation-5: -Count the total number of boxes in your Punnett Square. This gives you the total number of predicted offspring. Divide the (number of occurrences of the phenotype) by (the total number of offspring). Multiply the number from step 4 by 100 to get your percent.
