Chromosomal mutation - Definition and Examples - Biology Online
See more on biologyonline.comIn biology, a chromosomal mutation is the mutation of the chromosomal segments of the DNA strands. This can occur when the number of chromosomes or chromosome sets (ploidy) increases or decreases in a genome as well as when changes in chromosomes structure occur. Irregularities or accidents when cell di…Chromosomal inversion - Wikipedia
The suppressed recombination between inversion heterozygotes provides an opportunity for the independent evolution of the ancestral and inverted arrangements. At the beginning, the inverted arrangement lacks variation, while the ancestral one does not. If the inverted haplotype is not lost (e.g. due to drift), the variation in the inverted arrangement can increase over time, and recombination rate in the inverted region is somewhat restored as more homozygotes are introd…
