When the discovery is made by accident and mexpectedly the phenomenon is called:
1 mutation
2 serendipity
3 recombination
4 linkage
Explanation:
: When the discovery is made by accident and mexpectedly the phenomenon is called serendipity. It is an umplanned fortunate discovery. A few examples of serendipity discovery are the discovery of pericillin, heparin, dramamine, X-rays, the gram staining technique, the pancreas role in diabetes and the anesthetic effects of ether and ritrous oxide.

The mutagenic agent among following is
1 ethyl methane
2 ethylene
3 2,4-D
4 IAA Hary ana PMT-2009
Explanation:
: 2, 4-D is a mutagenic agent. It showed mutagenic and cytotoxic effects on V79 cells in culture in concentrations higher than 10 microgramsingl. In shallot root tips 2, 4-D causes changes in mitotic activity, as well as changes in chromosome and chromation structure and also changes during the cell cycle.

de Vries gave his mutation theory on organic evolution, while working on
1 Althea rosea
2 Drosophila melanogaster
3 Denothera lamarckiana
4 Fisum sativum JPMER-2007
Explanation:
: Hugo de Vries gave his mutation theory on organc evolution while working on Cenothera kamarchiana (everuing primrose). Hugo de Vries used the term mutation to describe phenotypic changes which were heritable. In addition to tecombination mutation is another pheromeron that leads to variation in DNA.

Mutation generally produces
1 tecessive genes
2 lethal genes
3 polygenes
4 dominant genes
Explanation:
: Mutations generally prochce recessive genes. This is due to recessive genes are those, which arte only expressed when both alleles of the gene are mutated.
