Population whose members reproduce sexually are termed as:
1 panimictic
2 ecotype
3 apomictic
4 amphimictic
Explanation:
Exp. C Population whose members reproduce sexually are termed as apomictic. Apomictic means reproduction in which plant can produce seeds without fertilization resulting in offspring that are genetically indentical to the parent plant.

Nucellar polyembryony is seen in the species of
1 Brassica
2 Citrus
3 Gossypium
4 Triticum
Explanation:
Nucellar polyembryony is seen in the species of citrus. Polyembryony is a process of formation of two or more embryo from a single fertilized egg. Gossypiun is a genus of herbs or shrubs of family malvaceae. Brassica is genus of plant family of cruciferous vegetables. Triticum is a tetraploid species of wheat.

Polyploidy can be produced artificially by
1 colchicine
2 inbreeding
3 line breeding
4 self pollination
Explanation:
Polyploidy can be produced artificially by colchicines. Polyploidy is a condition of possessing more than two complete sets of chromosomes. Colchicine presents the microtubule formation during cell division. Thus the chromosome do not segregate during anaphase. As a result, it induces multiple sets of chromosome. It is an alkaloid obtained from, Colchicum autumnale.

The number of capsomeres in the Tobacco mosaic virus capsid is
1 3210
2 1230
3 2130
4 2031
Explanation:
The number of capsomeres in the tobacco mosaic virus capsid is 2130 . Capsid is virus protein coat which is made up of capsomeres subunits. Tobacco mosaic virus (TMV) is a type of single stranded RNA virus. It has an impact on a wide variety of plants.

Nucleic acid is absent in
1 Virus
2 Viroid
3 Prion
4 Mycoplasma
Explanation:
Nucleic acid is absent in prion. Prion is a obligate parasite and is made up of only protein. It causes disease like scrapie in sheep, mad cow disease etc. Viroids were discovered by T.O. Diener in 1971 as an infectious agent and is smaller than a virus. It cause potato spindle tuber disease. It consist of nucleic acid but devoid of protein coat. Virus contains DNA or RNA as genetic material and a protein coat.
