translocation
the answer is TRANSLOCATION.
translocation
It's a translocation, specifically a balanced 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.
cross over
The exchange of segments is called translocation.
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.
DNA or genens these are the segments of the chromosome.
breaks off and attach to adjacent chromatids on the homologous chromosome
a. crossing over b. independent assortment or c. random fertilization
In prophase 1 crossing over causes chromosome segments to exchange and leads to new combinations of genes
It would appear you are speaking of crossing over which takes place in Prophase I of meiosis.
