Why did mendel self-pollinate tall `F_1` plants to get the `F_2` generation and crossed a pure breeding tall plant with a pure breeding dwarf plant to obtain `F_1` generation?

In order to obtain the FI generation Mendel pollinated a pure-breeding tall plant with a pure breeding dwarf plant. But for getting the F2 generation, he simply self- pollinated the tall FI plants.Why?

Answer the following Give the schematic representation of a cross between plants with yellow round seeds and plants with green wrinkled seed (the F_2 generation).

A pure tall plant with round seeds is crossed with dwarf plant having wrinkled seeds, how many kinds of offsprings are produced in F_1 and F_2 generation

A pure tall plant with red flowers is crossed with a pure dwarf plant with white flowers. What will the dihybrid ratio be when the genes interact with each other?

Two pea plants weresubjected to crosspollination. Of the183 plants produced in the next generation, 94 plants were found to be tall and 89 plants were found to be dwarf.Thegenotype of the two parental plants arelikely to be

Distinguish between: F_1 Generation and F_2 Generation

In a dihybrid cross, the total number of genotypes obtained in F_2 generation will be

Show the monohybrid cross between (RR) and (rr) and write the phenotypic and genotypic ratio of F_2 generation.

A homozygous tall pea plant with yellow seeds is crossed with a homozygous dwarf plant with green seeds: Give the phenotypic and genotypic ration of F_2 .

Questions based on paragraph A geneticist made a cross between two pea plants having axillary flowers (AA) and round shaped seeds (RR) with plants having terminal flowers (aa) and wrinkled seeds (rr). In F_1 generation, he obtained plants with axillary flowers and round shaped seeds. But in F generation, he obtained new combinations along with parental combinations. Mention the genotype of plants in F_2 generation obtained by geneticist.
