Question
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;
a) Give the phenotype and genotype of the F1 generation.
Which type of pollination has occurred to produce F1 generation?
b) Write the phenotypic ratio of the F2 generation
c) Write the possible combinations of the gametes that can be obtained if two F1 hybrid plants are crossed.
d) 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?
Solution
a)
- Phenotype of F1 generation: Pea plants with green and inflated pods.
- A genotype of F1 generation: GgIi
- Artificial cross-pollination has occurred to produce the F1 generation
b) The phenotypic ratio of the F2 generation is 9 : 3 : 3: 1
c) The possible combination of gametes that can be obtained if two F1 hybrid plants are crossed are as follows: GI, Gi, gI, gi
d) The two members of a pair of factors separate during the formation of gametes. This is Mendel’s law of ‘Segregation of Gametes’.
e) Pisum sativum
