When F1 plants were cross - pollinated with plants having tt genes, a total of 800 plants were produced. How many of these would be tall, medium height or short plants? Give the genotype of F2 generation.

Heterozygous tall plants were crossed with dwarf plants. What will be the ratio of dwarf plants in the progeny :-

Heterozygous tall plants were crossed with dwarf plants. What will be the ratio of dwarf plants in the progeny

Two pea plants were subjected cross pollination. Of the 183 plants produced in the next generation, 94 plants were found to be all and 89 plants were found to be dwarf. The genotypes of the two parental plants are likely to be:

On crossing two heterozygous tall plants (Tt), a total of 500 plants were obtained in F_(1) generation. What will be the respective number of tall and dwarf plants obtained of F_(1) generation ?

A plant with a genotype Aa Bb is crossed with a plant having the genotype aa bb. The genotype of F_(1) would be

In a cross 45 tall and 14 dwarf plants were obtained. Genotypes of parents are:

In a test cross progeny of pea plants ,all were bearing violet flowers.Give the genotypes of the parent pea plants.

If a dwarf plant is treated with gibberllins it becomes tall and plant now crosses with pure tall plant then progeny of first generation (F1) is
