- 1. A farmer crossed a round-shaped (T) and yellow-colored (Y) seed plant carrying yellow seeds (Y) and a wrinkled (t) and green-colored (g) seed plant. The traits of first plant is dominant over the second one. Fertilization of the first generation plants produced a total of 16 offsprings of the plants. What will be the genotypes and phenotypes of the offsprings. (Use punnette square to answer the question) Heterozygous lines for this cross Also, list up the Homozygous and4. What are the possible phenotypes and genotypes of the F1 generation if the P generation consisted of the following cross: a plant that is homozygous dominant for flower color and homozygous dominant for pod color was crossed with a plant that is heterozygous for flower color and homozygous dominant for pod color? Dominant for flower color – P (purple) Recessive for flower color = p (white) Dominant for pod color =G (green) Recessive for pod color = g (yellow) %3D P1: PP X GG Рр X GG PG PG PG PG PG PPGG PPGG PPGG PPGG PG PPGG PPGG PPGG PPGG PPGG PPGG Pp pG PPGG PpGG PPGG PpGG Genotypes: Phenotypes: Genotypic Ratio: Phenotypic 田2.
