Consumption of food, deficient in nutrients particularly micronutrients, proteins, and vitamins is called hidden hunger

For cereals, dwarfness is a desirable trait but for fodder plants tallness and branching are desirable. Other desirable traits include, higher yield, improved food quality, insect pest resistance, disease resistance to fungi, bacteria and viral diseases.

(i) Development of short duration, high yielding varieties of rice, including scented Basmati.
(ii) Development of light coloured wheat varieties (Sharbati Sonora, Pusa Lerma).
(iii) He also developed hybrid varieties of maize, jowar and bajra.

(i)Presence of required character not linked to any unwanted character.
(ii)Presence of required traits in existing and wild varieties.

Hybrid is formed by crossing two parents with different characters. Somatic hybrid is formed by protoplast fusion of two somatic cells.

(i) To guide the poultry farmers about proper construction and management of poultry farms for the prevention and control of poultry diseases and pests.
(ii) Vaccination of poultry birds to prevent the outbreak of diseases.
(iii) Early detection and rectification of the problems.
(iv) To instruct the poultry farmers to provide healthy feed and clean water to the birds.

The phenomenon being referred to is called 'Inbreeding depression' and results in loss of fertility and vigour. This happens because the recessive alleles tend to get together and express harmful effects in the progeny.

Use of gamma rays for crop improvement are not harmful because gamma rays introduce mutations.

1. Plant cells retain the power of division for comparavely longer periods than animal cells.
2. Animal cells become mature just after the embryonic stage and hence cannot be cultured.

Since the plants is produced by the fusion of two different somatic cells, it is called a somatic hybird
