Poly ethylene glycol (PEG) treatment is used in:A. Tissue cultureB. Organ cultureC. Embryo cultureD. Somatic hybridization |

Answer» Correct Answer - D The protoplasts carry negative charges on their surface and hence two protoplasts normally do not fuse when growing in culture medium. Its fusion is promoted by using electric shocks (electrofusion) or by using Poly Ethylene Glycol like chemical. They help in somatic hydridization and formation of cybrids, heterokaryocytes and synkaryocytes. |

Inbreeding is possible between two members of a:A. SpeciesB. GenusC. FamilyD. None of these |
|
Answer» Correct Answer - A Inbreeding is possible between the two members of a species. However, hybrids can be produced using plants of two different species (interspecific hybrids) or of two different genear (interspecific hybrids). Through somatic hybridization, now it is possible to hybridize cells of two different groups (algae and higher plants, or animal and plant cells, etc) |

Assertion: The removal of male of a hermaphrodite flowers is called emasulation. Reason: Emasculation is easy in case of large sized flowers.A. Both Assertion and Reason are true and Reason is correct explanation of Assertion.B. Both Assertion and Reason are true, but reason is not the correct explanation of AssertionC. Assertion is true, but the Reason is falseD. Assertion is false, but the Reason is true |
|
Answer» Correct Answer - B During hybridisation, removal of anthers from a bisexual flower to prevent the self-pollination is called emasculation. It is easy in case of large-sized flowers, while tedious, laborious and time consuming in case of small flowers. |
