Scientists are trying to transfer apomictic genes into hybrid varieties of several of our food and vegetable crops so that:

1. They get resistance against common pathogens

2. The yield of these plants can be increased many folds

3. Hybrid seeds need not be produced every year

4. Their germplasm is easily stored in labs for further research

The asexual production of seeds is called as:
1. Adventition
2. Fragmentation
3. Self-fertilization
4. Apomixis

Seed formation without fertilisation in flowering plants involves the process of

(1) budding

(2) somatic hybridization

(3) apomixis

(4) sporulation

Nucellar polyembryony is reported in species of

(1) Gossypium

(2) Triticum

(3) Brassica

(4) Citrus

Apomictic embryos in Citrus arise from

(1) synergids

(2) maternal sporophytic tissue in ovule

(3) antipodal cells

(4) diploid egg

Apomixis is

(1) formation of seeds by fusion of gametes

(2) formation of seed without syngamy and meiosis

(3) formation of seeds with syngamy but no meiosis

(4) none of the above

Match column I with column II and select the correct option from the given codes.

1. A - (iv), B - (ii), C - (iii), D - (i)

2. A - (iii), B - (ii), C - (i), D - (iv)

3. A - (i), B - (iv), C - (iii), D - (ii)

4. A - (ii), B - (iii), C - (i), D - (iv)

When a fern plant is developed from its prothallus without fertilisation? This pehnomenon is an example of

(1) parthenocarpy

(2) apogamy

(3) apospory

(4) organogenesis

Which of the following will lose its economic value if fruits are produced through parthenocarpy:

(1) Citrus             

(2) Banana           

(3) Grape             

(4) Pomegranate

Which of the following statements is false?
