translocation
translocation
An exchange of chromosome segments is called a translocation. In genetics, it refers to a chromosome abnormality caused by rearrangement of parts between nonhomologous chromosomes.
the answer is TRANSLOCATION.
It's a translocation, specifically a balanced translocation.
cross over
Translocation is when nonhomologous chromosomes exchange segments, like when chromosome 1 exchanges parts with chromosome 5. Inversion is when broken segments of the chromosome is inserted backwards.
During meiosis, chromosome exchange occurs at the chiasmata, which are points of crossing over between non-sister chromatids. The exchange involves the exchange of genetic material between homologous chromosomes, not specifically at the centromere or telomere regions.
It would appear you are speaking of crossing over which takes place in Prophase I of meiosis.
breaks off and attach to adjacent chromatids on the homologous chromosome
a. crossing over b. independent assortment or c. random fertilization
Crossing over: exchange of parts of DNA in a homologous chromosome in the area where they come in contact with each other. Then this chromosome splits, during meiosis, to form a daughter cell (gamete) with a haploid number of chromosomes. During fertilization, the two gametes fuse into one cell containing now a diploid number of chromosomes. This process leads to genetic diversity and variation.
Recombination may be caused by loci on different chromosomes that sort independently or by a physical crossing over between two loci on the same chromosome, with breakage and exchange of strands of homologous chromosomes paired in meiotic prophase I.
