please answer questions 2 and 3 if you dont mind? please show the work...

2. In garden peas axial flower position (A) is dominant and terminal fnower position (a) is recessive. Tall vine (T) is dominant and short vine () is recessive. A plant homozygous for tall vine and axial flowers was crossed with a plant having short vines and terminal nowers. What are the possible phenotypes and genotypes of the offspring? Parental Genotypes and gametes . For the homozygous for tall vine and axial flowers The genotype is and the possible gametes is/are For the short vines and terminal flowers The genotype is and the possible gametes is are .Complete the dihybrid cross What are the possible phenotypes and genotypes of the offspring? Geneotypes of Possible offspring produced by a dihybrid cross

Explanation / Answer

Axial flower = A, terminal flower=a, A is dominant to a

Tall vine = T, short vine =t, T is dominant to t

TTAA X ttaa

Parental genotype- tall, axial= TTAA

                                     Short, terminal = ttaa

3. Parental genotype = TtAa

                      Phenotype= tall, axial
