The term chiasma is linked if not identical to chromosomal crossover.
Deletions can be caused by errors in chromosomal crossover during meiosis.
It is a type of chromosomal crossover between homologous sequences that are not paired precisely.
Genes on the same chromosome would theoretically never recombine, however, were it not for the process of chromosomal crossover.
Several different processes contribute to reassortment, including assortment of chromosomes, and chromosomal crossover.
This often results in chromosomal crossover.
The most common form of chromosomal crossover is homologous recombination, where the two chromosomes involved share very similar sequences.
It allows matching-up of homologous pairs prior to their segregation, and possible chromosomal crossover between them.
The probability of chromosomal crossover occurring between two given points on the chromosome is related to the distance between the points.
Normally, the chestnut and roan alleles would be separated during chromosomal crossover, but these two linked genes will usually remain together.
In eukaryotes, recombination also occurs in meiosis, where it facilitates chromosomal crossover.
Chromosomal crossover is when two DNA helices break, swap a section and then rejoin.
Chromosomal crossover begins when a protein called Spo11 makes a targeted double-strand break in DNA.
Chromosomal crossover refers to recombination between the paired chromosomes inherited from each of one's parents, generally occurring during meiosis.
This process of chromosomal crossover generally occurs during meiosis, a series of cell divisions that creates haploid cells.
Instead, paired chromosomes exchange parallel pieces of DNA, a process called chromosomal crossover, prior to being passed on to the next generation.
Recombination frequency (θ) is the frequency with which a single chromosomal crossover will take place between two genes during meiosis.
For those primary oocytes that continue to develop in each menstrual cycle, however, synapsis occurs and tetrads form, enabling chromosomal crossover to occur.
Chromosomal crossover (or crossing over) is the exchange of genetic material between homologous chromosomes that results in recombinant chromosomes.
It does so by facilitating chromosomal crossover, in which regions of similar but not identical DNA are exchanged between homologous chromosomes.
In this case there is an unreciprocal exchange of genetic code between the chromosomes, in contrast to chromosomal crossover, because genetic information is lost.
The enzymatic machinery responsible for this repair process is nearly identical to the machinery responsible for chromosomal crossover during meiosis.
In genetics, the coefficient of coincidence (c.o.c.) is a measure of interference in the formation of chromosomal crossovers during meiosis.
The following year, McClintock and Creighton proved the link between chromosomal crossover during meiosis and the recombination of genetic traits.
Depending on how the two junctions are cut by enzymes, the type of homologous recombination that occurs in meiosis results in either chromosomal crossover or non-crossover.
