Title: Select the genotypes and phenotypes seen in the F2. (MG Chpt 21 Due Tomorrow!) Post by: darwincalledit on Jun 23, 2014 Two pure-breeding wheat strains, one producing dark red kernels and the other producing white kernels, are crossed to produce F1 with pink kernel color. When an F1 plant is self-fertilized and its seed collected and planted, the resulting F2 consist of 160 plants with kernel colors as shown in the table.
A: Based on the F2 progeny, how many genes are involved in kernel color determination? Answer: 2 B: How many additive alleles are required to explain the five phenotypes seen in the F2? Answer: 4 C: If alleles that add to kernel pigment are designated with a "1", and alleles that do not add to kernel pigment are designated with a "2", enter the genotypes for the dark red parent and then the genotype for the white parent. Answer: A2A2B2B2 and A1A1B1B1 D: Give genotype(s) for the F1. Answer: A1B1A2B2 E: What will be the color of the F1 ? Answer: Pink Question I need help with!!! F: Select the genotypes and phenotypes seen in the F2? A: White A1A1B1B1 Red A1A2B1B1 and A1A1B1B2 Light pink A1A1B2B2 , A1A2B1B2 and A2A2B1B1 Pink A1A2B2B2 and A2A2B1B2 Dark red A2A2B2B2 B: White A1A1B1B1 Red A1A2B1B1 and A1A1B1B2 Pink A1A1B2B2 , A1A2B1B2 and A2A2B1B1 Light pink A1A2B2B2 and A2A2B1B2 Dark red A2A2B2B2 . C: Dark red A1A1B1B1 Red A1A2B1B1 and A1A1B1B2 Pink A1A1B2B2 , A1A2B1B2 and A2A2B1B1 Light pink A1A2B2B2 and A2A2B1B2 White with the genotype A2A2B2B2 D: Dark red A1A1B1B1 Red A1A2B1B1 and A1A1B1B2 Light pink A1A1B2B2 , A1A2B1B2 and A2A2B1B1 Pink A1A2B2B2 and A2A2B1B2 White A2A2B2B2 .

Post by: darwincalledit on Jun 23, 2014 Yeah thanks but I already have Parts A-E answered. I actually need help with Part F, the question that's asking about the geno and phenotypes of the F2.
F: Select the genotypes and phenotypes seen in the F2? A: White A1A1B1B1 Red A1A2B1B1 and A1A1B1B2 Light pink A1A1B2B2 , A1A2B1B2 and A2A2B1B1 Pink A1A2B2B2 and A2A2B1B2 Dark red A2A2B2B2 B: White A1A1B1B1 Red A1A2B1B1 and A1A1B1B2 Pink A1A1B2B2 , A1A2B1B2 and A2A2B1B1 Light pink A1A2B2B2 and A2A2B1B2 Dark red A2A2B2B2 . C: Dark red A1A1B1B1 Red A1A2B1B1 and A1A1B1B2 Pink A1A1B2B2 , A1A2B1B2 and A2A2B1B1 Light pink A1A2B2B2 and A2A2B1B2 White with the genotype A2A2B2B2 D: Dark red A1A1B1B1 Red A1A2B1B1 and A1A1B1B2 Light pink A1A1B2B2 , A1A2B1B2 and A2A2B1B1 Pink A1A2B2B2 and A2A2B1B2 White A2A2B2B2 .
