Final answer:
If cell division fails to occur following DNA replication in a germ line cell, it can lead to various consequences such as the accumulation of mutations and the development of genetic diseases. On the other hand, if atypical daughter cells are able to undergo further cell divisions, it can result in tumor growth.
Step-by-step explanation:
If cell division fails to occur following DNA replication in a germ line cell, several consequences can arise. One possibility is the accumulation of mutations in the DNA that may lead to genetic diseases. Additionally, the lack of cell division can result in the failure to propagate certain mutations, preventing harm from coming to the organism. However, if atypical daughter cells are able to undergo further cell divisions, subsequent generations may accumulate even more mutations, potentially leading to tumor growth.
