Chapter 14, Problem 3GP
True-breeding tall red-flowered plants are crossed with dwarf white-flowered plants. The resulting F1 generation consists of all tall pink-flowered plants. Assuming that height and flower color are each determined by a single gene on different chromosomes, predict the results of an F1 cross of dihybrid plants. Choose appropriate symbols for the alleles of the genes. List the

Assume that smooth seed coats are dominant over rough seed coat.
If two pea plants that are both Heterozygous for seed coats are crossed, what do you expect in the offspring (the f1 generation)? Specifically, what genotypes, what phenotypes, and in what ratios? (Use S for the smooth seed coat and s for the rough seed coat.) (Again, it is helpful to write out all the possible genotypes and give the phenotype for each genotype before answering the specific question.) Be careful in writing capital S and lower case.
In certain plants, tall (T) is dominant to short (t). If a heterozygous plant is crossed with a homozygous short plant, what is the probability that the offspring will be short? Show the punnett square please.
In the tomato, yellow flowers (Y) is dominant to white flowers (y). A true-breeding yellow flowered strain is crossed with a true-breeding white flowered strain.A. If the F1 generation is self crossed, what will be the genotypes and phenotypes of the progeny and in what portions are they expected?
B. If an F1 plant were crossed with a plant from true-breeding white flowered strain, what will be the genotypes and phenotypes of the progeny and in what portions are they expected?

Seeds may be round (R) or wrinkled (r), with the allele for round seeds being dominant. Alleles for seed color are yellow and green, with the green allele (y) recessive to the yellow (Y) allele.
