Haploids are more suitable for mutation studies than the diploids. This is because
1 Haploids are more abundant in nature than diploids
2 Haploids are reproductively more suitable than diploids
3 All mutations whether dominant or recessive are expressed in haploids.
4 Mutagens penetrate in haploids more effectively than in diploids
Explanation:
Haploid plants are formed in large number by anther and ovary cultures. As haploids have only one set of chromosome hence alleles. So, they can be used for isolation of mutants, after all, even recessive mutant alleles would be expressed in the mutagen treated generation itself.

Which of the of the following statements about mutations is false?
1 Mutations are the source of new alleless for genes.
2 Mutations are random events and can happen in any cell at any time.
3 Organisms are able to create mutations to meet their specific needs.
4 Most mutations random are tend to be harmful or have no effect on organisms.
Explanation:
Mutations are random and cannot be created or decided.

Absence or excess or abnormal arrangement of one or more chromosomes results in
1 Point mutation
2 Chromosomal disorders
3 Mendelian disorders
4 Gene mutation
Explanation:
Since genes are known to be located on chromosomes, alteration in chromosomes results in abnormalities or aberrations.

Which is the most common mechanism of genetic variation in the population of a sexually reproducing organism
1 Recombination
2 Chromosomal aberrations
3 Genetic drift
4 Transduction
Explanation:
Recombination is a very important origin of genetic variation between individuals of sexually reproducing species, and the driving force for the process of natural selection.
