They have a great effect on recombination because during crossover in meiosis, one chromosome will be forced to make a loop.
Although there is no loss or gain of genetic associated with these, there is almost certainly a positive or negative position effect on the phenotype. They have a great effect on recombination because during crossover in meiosis, one chromosome will be forced to make a loop. This will result in gametes that will not have a full set of genes. Along with translocations, they are the most important physical alterations of chromosomes. FTP name this condition in which the orientation of a portion of a chromosome is reversed.
