A pea plant which is homozygous for Green pods which are inflated

Human Evolution (10)

A pea plant which is homozygous for Green pods which are inflated [GGII] is crossed with a homozygous plant for yellow pods which are constricted [ggii]. Answer the following questions:

  1. Give the phenotype and genotype of the F1 generation. Which type of pollination has occurred to produce F1 generation?
  2. Write the phenotypic ratio of the F2 generation.
  3. Write the possible combinations of the gametes that can be obtained if two F1 hybrid plants are crossed.
  4. State Mendel’s law of ‘Segregation of Gametes’.
  5. What is the scientific name of the plant which Mendel used for his experiments on inheritance?

Answer

  1. Phenotype: All have green, inflated pods.
    Genotype: GgIi, Cross pollination
  2. 9 : 3 : 3 : 1
  3. GI, Gi, gI, gi
  4. Two members of a pair of factors separate during gamete formation./The two alleles of a trait separate during gamate formation.
  5. Pisum Sativum
