Punnett Squares Crosses Involving One Trait Worksheet Answer Key - Allele must be boring because the allele for boring (. Using the punnett square below, predict the frequencies of the genotypes and phenotypes of the offspring from dark brown parents two who are heterozygous (i.e., dd genotypes). For example, when a homozygous red snapdragon is crossed with a homozygous white snapdragon, all of the heterozygous offspring are pink. The document is a punnett square practice worksheet that provides examples of monohybrid and dihybrid crosses involving various traits in different organisms.
