this slide is about mutation especially on gene and chromosomal mutation for intermediate students. students can take benefit from it

1. Chromosomal mutation
Dambar Singh Khatri

2. Chromosomal mutation
• It takes place by two types
• Change in chromosomal structure
• Change in chromosomal number

3. Change in chromosomal structure
• Duplication
• Deletions
• Inversions
• Translocations

4. Change in Chromosome number and sets
• A.Euploidy
• Monoploidy(haploidy)- loss of complete one set of chromosome from diploid cell.
• Polyploidy- multiple set of chromosome.
• B. Aneuploidy
• Monosomy- loss of single chromosome from diploid set. 2n-1
• Nullisomy- loss of a pair of chromosome.2n-2
• Trisomy- a single chromosome added to chromosome set.2n+1
• Tetrasomy- diploid organism having two extra chromosome.2n+2
• Double trisomy- two different chromosome consists of trisomy condition.2n+1+1
