Assertion : The size of VNTR varies from 0.1 to 20kb.
Reason : The number of tandem repeat show very high degree of polymorphian.

VNTR varies in size from 0.01 to 200kb.

State trur and false VNTR varies in size from 0.01 to 200kb.

Assertion :- DNA fingerprinting involves identifying differences in some specific regions in DNA called as repetitive DNA sequences. Reason : These sequences show high degree of polymorphism & from the basis of DNA fingerpringing.

Assertion : A bird perches on a high power line and nothing happens to the bird. Reason : The level of bird is very high from the ground.

Assertion: The sizes of crows and parrots are not very different yet their life spans shows a wide difference. Reason: Life spans of organisms are not necessarily correlated with their sizes.

Assertion: The sizes of crows and parrots are not very different yet their life spans shows a wide difference. Reason: Life spans of organisms are not necessarily cor related with their sizes.

Assertion : When the DNA sequences of two people are cut using the same restriction enzyme, the length and number of fragments obtained are different for both. Reason : DNA sequence is arranged tandemly in many copy numbers which varies from chromosome to chromosome in an individual, showing high degree of polymorphism.

Reason : DNA sequence is arranged tandemly in many copy numbers which varies from chromosome to chromosome in an individual, showing high degree of polymorphism.

Assertion : 1000 is the successor of 999. Reason : We get the successor of a whole number, if we subtract 1 from it.
