Presentation transcript:

Practice #1 Ii x II inflated pod vs constricted

Practice #2 Aa x aa axial vs terminal

Practice #3 Tt x Tt tall vs short

Practice #4 Cross two heterozygous green pea pod plants.

Practice #5 Cross a plant that is heterozygous for axial flowers with a plant that has terminal flowers.

Practice # 6 Cross a homozygous tall plant with a short plant.

Practice # 7 Cross a heterozygous inflated pod plant with a constricted pod plant.

Practice #8 When a tall plant is crossed with a short plant, some of the offspring are short. What are the genotypes of the parents and offspring? What is the phenotype ratio in the offspring?

Practice # 9 Three-fourths of the plants from a cross of two unknown pea plants have axial flowers, the rest have terminal flowers. What are the genotypes of the parents?

Practice #10 What cross would result in ½ the offspring having green pods and ½ having yellow pods? End monohybrid crosses

Practice #11 What would be the result of a cross between a homozygous tall and purple flowered plant with a heterozygous tall and purple flowered plant?

Practice #12 Cross a homozygous tall and yellow pea plant with a homozygous short and green pea plant. Then cross the F1 generation to determine the F2 genotype and phenotype possibilities.

Practice #13 Cross a homozygous axial and constricted plant with a homozygous terminal and inflated plant.

Practice #14 What would the parents be if you got the following results: 9/16 tall and round 3/16 tall and wrinkled 3/16 short and round 1/16 short and wrinkled

Practice # 15 What would the parents be of a cross that produces green pods with round seeds and yellow pods with wrinkled seeds?
