Reduction of crossing over within an inversion loop in inversion heterozygotes due to physical constraints during synapsis. Crossing over within an inversion loop, when it does occur, leads to defective (deleted and duplicated) crossover chromosomes ...

Chromosomal crossover
Chromosomal crossover is the process by which two chromosomes, paired up during Prophase I of meiosis, exchange some distal portion of their DNA.
Crossover The reciprocal exchange of genetic material between homologous chromosomes in meiosis. A point along the length of a meiotic bivalent where the homologous chromosomes can be seen to have exchanged chromatids.
One crossover event inhibits the chances of another crossover event. Also known as positive interference. Negative interference increases the chance of a second crossover.

However, crossover is the key element that distinguishes genetic algorithms from other methods such as hill-climbers and simulated annealing.
But a second crossover would undo the effect of the first and restore the parental combination of alleles. These would show up as nonrecombinants.
Crossovers -- the exchange of genetic material between two paired chromosome during meiosis.
Complete linkage describes the inheritance patterns for 2 genes on the same chromosome when the observed frequency for crossover between the loci is zero. dioecious Organisms produce only one type of gamete; i.e. humans dominant trait.
The chromatids crossover, break and rejoin. At least one crossing over event per chromosome arm is obligatory for successful meiosis.
They get inherited together because they're not generally crossovers or recombinations between these markers or between these different polymorphisms because they are very, very close.

Fain and Richard Kouri (BIOS Corporation) have constructed crossover maps for all meioses in 40 Centre d'Etude du Polymorphisme Humain (CEPH) reference families in preparation for high-resolution genetic mapping using meiotic mapping panels.
Genetic interference
Positive interference: the interaction between crossovers such that the occurrence of one exchange between homologous chromosomes reduces the likelihood of another in its vicinity.
genetic maps Diagrams showing the order of and distance between genes; constructed using crossover information.
genetics The study of the structure and function of genes and the transmission of genes from parents to offspring.
Unequal cross-over
A recombination event that occurs between DNA molecules that are not fully aligned. For example, a crossover may occur between repeated DNA sequences resulting in the deletion or duplication the intervening DNA sequence.
Balanced lethal: Lethal mutations in different genes on the same pair of chromosomes that remain in repulsion because of close linkage or crossover suppression.
