c.o.c. = actual double recombinant frequency / expected double recombinant frequency. Interference is then defined as follows: [1] interference = 1 − c.o.c. This figure tells us how strongly a crossover in one of the DNA regions (AB or BC) interferes with the formation of a crossover in the other region.
A typical characteristic of a 2-way speaker is that at the crossover frequency, due to the physical distance between the centres of the woofer and tweeter, the sound that emanates from the combination is not omni-directional, but lobed. Within the region of the lobe the sound level, at the crossover frequency is much higher as compared to ...
In genetics, the crossover value is the linked frequency of chromosomal crossover between two gene loci ().For a fixed set of genetic and environmental conditions, recombination in a particular region of a linkage structure tends to be constant and the same is then true for the crossover value which is used in the production of genetic maps.
Because there is a small probability of recombination at any location along a chromosome, the frequency of recombination between two locations depends on the distance separating them. [citation needed] Therefore, for genes sufficiently distant on the same chromosome, the amount of crossover is high enough to destroy the correlation between alleles.
The linked frequency of crossing over between two gene loci is the crossing-over value. For fixed ... The difference between gene conversion and chromosomal crossover.
In genetics, a centimorgan (abbreviated cM) or map unit (m.u.) is a unit for measuring genetic linkage.It is defined as the distance between chromosome positions (also termed loci or markers) for which the expected average number of intervening chromosomal crossovers in a single generation is 0.01.
By comparing the parental and double-crossover phenotypes, the geneticist can determine which gene is located between the others on the chromosome. The recombinant frequency is the ratio of non-parental phenotypes to total individuals.
A consequence of this method of counter-propagating beams on a system with more than two states is the presence of crossover lines. When two transitions are within a single Doppler-broadened feature and share a common ground state, a crossover peak at a frequency exactly between the two transitions can occur.
