Fusion of somatic cells to form cell hybrids
A) is useful for mapping genes to chromosomes, as chromosomes are identified as they are lost from the hybrid cell.
B) can only be achieved for cells of closely related organisms (same order).
C) creates stable heterokaryon cells that can be used in analysis of homologous chromosome structure.
D) as chromosomes are identified as they are lost from the hybrid cell.
E) All of the above are correct.

Question

Quizplus · Accepted Answer

Fusion of somatic cells to form cell hybrids is useful for mapping genes to chromosomes because as the hybrid cells divide, they tend to lose chromosomes randomly. By correlating the presence or absence of specific chromosomes with the expression of certain genes, researchers can map genes to specific chromosomes.
