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?
Choose the correct answer:
Mendel used ______ pairs of a characters for his experiments.
______ pairs of contrasting characters in pea plants were studied by Mendel in his experiments.
The inheritance pattern of a gene over generations among humans is studied by the pedigree analysis. Character studied in the pedigree analysis is equivalent to ______.

To study the natural phenomenon of inheritance, Mendel selected pea plants. Which of the following properties were suitable for their studies?
(i) Plants would easily self-pollinate or cross-pollinate in nature.
(ii) Plants were easily grown in garden soil with a considerably shorter generation time.
(iii) Pea plants do not require true-breeding for hybridization experiments.
(iv) Many parts of the plant such as pod, seed, flower, cotyledons showed distinct phenotypes.
Give reasons for the appearance of new combinations of characters in the F2 progeny.
