Translocations -a mutations occur in chromosomes, wherein chromosomesegments change positions. Mutations in a gene’s DNA sequence can alter the amino acid sequence of the protein encoded by the gene. Inversion-A mutation is a permanent change in the DNA sequence of a gene. Chromosomal duplication, which can cause Bloom and Rett syndrome.
Gene duplication, a process which can result in free mutation. A deletion mutation can remove a single nucleotide, or entire sequences of nucleotides. Haploidy – reduction of a normal number jf chromosomes in 2 times when the zygote has number of chromosomes 1nĪ deletion mutation is a mistake in the DNA replication process which removes nucleotides from the genome. Polyploidy is the process of genome doubling that gives rise to organisms with multiple sets of chromosomes. These changes are most often brought on by problems that occur during meiosis.Īneuploidy is the presence of an abnormal number of chromosomes in a cell, for example a human cell having 45 or 47 chromosomes instead of the usual 46.
This type of mutation arises as a result of errors in the divergence of chromosomes in the process of meiosis.Ĭhromosomal mutations is an unpredictable change that occurs in a chromosome. Genomic mutations affect not individual genes and parts of the chromosome, but the whole genome of the cell, as a result, the number of chromosomes changes. Determines the types and differences of mutationsGet information about mutagenic factorsĪ gene mutation is a permanent alteration in the DNA sequence that makes up a gene, such that the sequence differs from what is found in most people.
