A garden pea plant produces inflated yellow pods. Another pea plant produces constricted green pods. Indetify the dominant traits.

A garden pea plant produces white axial flowers. Another pea plant produces violet terminal flowers. Identify the dominant traits.

A garden pea plant produced round green seeds. Another pea plant produced wrinkled yellow seeds. Indentify the dominant traits.

Why is plant food not produced in any other parts of the plant except the green ones?

A homozygous pea plant with green pods was crossed with a homozygous pea plant with yellow pods. F_1 produced 883 plants with green pods and 220 plants with yellow pods. State the generalization proposed by Mendel on the basis of the above statement.

A single pea plant in the backyard produces pods with viable seeds but the papaya tree does not. Give reason.

Write short note on Why are green plants called producers?

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 .

A cross between a homozygous pea plant with a dominant character and a homozygous pea plant with a recessive character showed F_1 hybrids expressing the dominant character only. Which law of Mendel's applicable to the above statement?

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

Read the following paragraph and answer the questions based on it. Rhizobium produce nitrogenous compounds from atmospheric nitrogen. However, for this process of nitrogen fixation, they need leguminous plants like beans, sweet pea, soyabean, etc. as ‘host’. Rhizobium living in root nodules supply nitrates, nitrites and amino acids to that plant and in exchange get energy in the form of carbohydrates from it. Such a mutually beneficial relationship is called symbiosis. Beans and pulses are rich in proteins due to the nitrogenous compounds made available by Rhizobium. After harvesting a leguminous crop, the left-over roots and other plant parts are deliberately dumped in farm soil to maintain its bacterial population. The use of Rhizobium has helped to reduce the use of chemical fertilizers and thereby their adverse effects. It has also helped to reduce expenses on fertilizers and thus works to the benefit of farmers. What is provided by the host plant to the Rhizobium bacteria?
