  2. Coefficient of coincidence - Wikipedia

    en.wikipedia.org/wiki/Coefficient_of_coincidence

    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.

  3. Loudspeaker time alignment - Wikipedia

    en.wikipedia.org/wiki/Loudspeaker_time_alignment

    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 ...

  4. Crossover value - Wikipedia

    en.wikipedia.org/wiki/Crossover_value

    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.

  5. Genetic recombination - Wikipedia

    en.wikipedia.org/wiki/Genetic_recombination

    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.

  6. Chromosomal crossover - Wikipedia

    en.wikipedia.org/wiki/Chromosomal_crossover

    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.

  7. Centimorgan - Wikipedia

    en.wikipedia.org/wiki/Centimorgan

    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.

  8. Three-point cross - Wikipedia

    en.wikipedia.org/wiki/Three-point_cross

    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.

  9. Saturated absorption spectroscopy - Wikipedia

    en.wikipedia.org/wiki/Saturated_absorption...

    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.
