1. in corn, the kernels represent the offspring of agenetic cross between two corn plants. the kernelsare the seeds that produce the next generation. eachkernel contains all of the genetic information that willdetermine the characteristics of a new corn plant.
2. in corn, kernels can be purple or yellow. the dominantallele, p, produces a purple kernel. the recessive allele, p, produces a yellowkernel. so, if a kernel contains at least one dominant allele, p, it will be purple. if it contains two recessive alleles, pp, it will be yellow.
3. the corn kernels on your cob are the f2 generation and were obtained by crossingtwo f1 plants. the f1 plants were produced by crossing two parent plants, also knownas the p (parent) generation.
4. trace the inheritance of the dominant and recessive alleles for kernel color byworking backwards. use the think it over questions to accomplish this task.
think it over

what are the possible allele combinations present in the f2 corn kernels? in otherwords, what alleles does a yellow kernel have? what alleles may a purple kernel have?
