Aplant breeder produced a purple flower by crossing a red parent with a blue parent. use rr as the genotype for the red parent and bb for the blue parent. complete the punnett square to show the resulting genotypes and phenotypes of the offspring.

gamete allele: r gamete allele: r

gamete allele: b genotype: rb genotype: rb
phenotype: purple phenotype: purple
gamete allele: b genotype: rb genotype: rb
phenotype: purple phenotype: purple

In a classic experiment using pea shape, mendel conducted two separate genetic crosses. in the first cross the parent plants were “true breeding” for pea shape; one had round peas ( r )and the other had wrinkled (r). the first cross produced a filial 1 generation of all round peas. in the second cross, mendel bred plants from the filial 1 generation. this cross produced different results. out of approximately 1000 plants, about 75% were round and 25% were wrinkled.
