Question

In a nonreciprocal interchomosomal translocation, a segment of a chromosome is 1. transferred to a different chromosome without a reciprocal exchange of genetic material 2. transferred to a new location on the same chromosome without a reciprocal exchange of genetic material 3. exchanged with an identical segment on a sister chromatid 4. exchanged with an identical segment on a different chromosome.

Answer 1

Answer:

Transferred to a different chromosome without a reciprocal exchange of genetic material

Explanation:

Translocation is one of the structural abnormalities of chromosomes. During translocation, a segment from the chromosome breaks off and attaches to the non-homologous chromosome. Translocation can be reciprocal or nonreciprocal.

In reciprocal translocation, the exchange of chromosomal segments occurs between two non-homologous chromosomes. On the other hand, the nonreciprocal translocation, one chromosome loses its segment to a non-homologous chromosome but does not get the same from the recipient chromosome.
