This tutorial looks at the effects of chromosomal mutations, such as in this mutation, the mutants genes are displayed twice on the same chromosome due to duplication of these genes.
A portion of the chromosome has broken off, turned upside down and reattached, therefore the genetic material is backward. Gene mutation is source of genetic variance and genetic polymorphism, these gene mutations can arise. A geneticist found that a particular mutation had no effect on the protein coded by a gene.
Chromosomal mutations are any alterations or errors that occur on a chromosome.
Gene and chromosome mutation worksheet (reference pgs. A mutation is a change or alteration happens in a dna, gene, or chromosome due to intrinsic or extrinsic factors such as an error in replication or exposure to uv light, respectively. Chromosomes switch places (reciprocal exchange). However, changes in the genome do sometimes occur.
