Detailed explanation-1: -An inversion occurs when a chromosome breaks in two places; the resulting piece of DNA is reversed and re-inserted into the chromosome. Genetic material may or may not be lost as a result of the chromosome breaks.
Detailed explanation-2: -Inversions can generate structural problems with meiosis, as with some pericentric inversions. Alternatively, a breakpoint can disrupt an open reading frame or alter gene expression. The consequences can be deleterious, as in some human genetic diseases [6], but in other cases could cause an adaptive mutation.
Detailed explanation-3: -Inversion events can produce hybrid genes that have varying portions of two genes, not necessarily half and half. However, inversion events can connect half of a gene with a region of DNA that has no genes. The result would be a broken gene.
Detailed explanation-4: -A temperature inversion is a layer in the atmosphere in which air temperature increases with height. An inversion is present in the lower part of a cap.
