Solution

The correct option is A A- 2, B- 5, C- 6, D- 3, E- 8, F- 4, G- 9, H- 1, I- 10, J- 7
Mendel performed Reciprocal crosses between plants having alternate traits of a character, e.g., tall and dwarf, coloured flower and white flower.

For this he removed Anthers (emasculation) from 50% of the flowers of each type and used them as female parents.

Pollen from the other trait were collected and dusted over the stigma of these flowers. The pollinated flowers were covered with paper bags and allowed to form pods with seeds.

The cross involving two traits of a single character is called Monohybrid cross

Cross involving traits of two characters is known as Dihybrid cross

The seeds of the cross were collected and sown next year. The plants were hybrid in nature. They constituted the First filial generation or F1 generation.

Self Breeding for F2 and F3 generations. Plants of F1 generation were allowed to perform Self pollination or self fertilization.

Mendel collected seeds of the new generations. Plants raised from them were called Second filial

or F2 Generation

Further self pollination of F2 plants produced F3 Third filial generation

Q. In an experiment, a flower from the pea plant (pure line) that produces constricted pods was emasculated and bagged. Meanwhile, pollen from another pea plant (pure line) that produces inflated pods was collected and dusted on the stigma of the emasculated flower. The flower, after pollination, was rebagged.
Assuming that the plants were otherwise similar in all other characters, predict the phenotype of the offspring of the

F_{1}

generation.

In a pea plant, flower colour purple is dominant over white and fruit shape round is dominant over wrinkled. Crossing was performed between two pure lines-one having purple flower and round fruit, and another with white flower and wrinkled fruit. Plants of F1 were allowed to self-fertilize, and about 960 plants survived in F2. If the traits follow Mendelian inheritance, the number of plants in F2 that would have yellow flowers and round fruits in F2 are:
