Allelic sequence variation where more than one variant allele at a locus in a human population with a frequency greater than 0.01 is referred to as
1 DNA polymorphism
2 multiple allelism
3 SNP
4 EST JPMER-2014
Explanation:
: Allelic sequerce variation where more than one variant allele at a locus in a human population with a frequency greater than 0.01 is referred to as DNA Folymorphistn. DNA polymorphism is the presence of two or more different alleles for a particular gene in a population. Alleles are different forms of the same gene DNA folymorphisms can be caused by mutations, which are changes in the DNA sequence.

Which of the following is generally used for induced mutagenesis in crop plants?
1 X-rays
2 UV (260 mm )
3 gamma rays (from cobalt 60)
4 alpha particles
Explanation:
: Gamma rays (from cobalt 60) is generally sed for induced mutagenesis in crop plants. Induced nutagenesis is one of the most efficient tools used for the identification of key regulatory genes and molecular mechanisms. - X-rays, \(\beta\)-rays and \(\gamma\)-rays are used as mutagens in such materials where nuclear is deep seated i.e. - Seed, Stem cuting.

What base is responsible for hot spots for spontaneous point mutations?
1 Aderine
2 Guarine
3 5-bromouraci1
4 5-methyl cytosine
Explanation:
: 5-Bromouracil is the brominated form of uracil that replace thymine in DNA. Aderine can pair with 5 -bromouracil instead of thymine and this can induce point mutations. Primiple of Inheritance and Variation

What change occurs by changing one base in DNA
1 Always a change of one amino acid in protein
2 Change in complex sequence of amino acid
3 Always a change in property of protein
4 Does not necessarily change the phenotype
Explanation:
: With base substitution mutations, only a single mucleotide within a gene sequence is change, so only one codon is affected, only a single codon in the gene sequence is changed in base substitution but do not necessarily change the phenotype.

If a diploid cell is treated with colchicines then it becomes :-
1 Triploid
2 Tetraploid
3 Diploid
4 Monoploid
Explanation:
: If a cliploid cell is treated with colchicines then it becomes tetraploid. It is an alkaloid from seeds of Colchicum autumnal. It has the urique property of arresting the spindle formed in the cell division process.
