Assignment - 1 1. A heterozygous pea plant that is tall is allowed to self-fertilize. What is the ratio of the phenotypes and genotypes in the F2 generation? Show the phenotypes and the genotypes of offsprings using Punnett Square. Phenotype: 3 Tall :1 Dwarf Genotype: 1 homozygous dominant (TT) : 2 heterozygous dominant (Tt) : 1 homozygous recessive (tt) 2. A pea plant is heterozygous for two genes ( Aa,Pp ),axial flower position, purple color of flower. If this plant is self-fertilized, what are the predicted phenotypes of the offspring and what fraction of the offspring will occur in each category?
