How many generations? edit

So how many cell generations are there in the germ line per human or other animal generation? -- 92.229.177.182 (talk) 10:04, 3 April 2009 (UTC)Reply

this reads like an encyclopedia edit

this reads like its drafted directly from the pages of a scientific encyclopedia. it is very well scripted and presented, and someone has the nerve to say that its too technical?
unfortunately, not everyone realizes that scientific dialogue is generally complex. this is one of the best pages on wiki, if it is in fact an originally compiled document. that would be what i would question: not its complexity, but its originality versus plagiarism!
anyone else with me on that? —Preceding unsigned comment added by Proud kraut (talkcontribs) 04:32, 11 April 2009 (UTC)Reply

Typo? edit

"Multicellular eukaryotes are made of one fundamental cell types. Germ cells ... Somatic cells ... "

Shouldn't this read: "Multicellular eukaryotes are made of TWO fundamental cell types. Germ cells ... Somatic cells ... "

Possible addition to the Specification section edit

After the initial couple paragraphs, I would like to add this:

It is speculated that induction was the ancestral mechanism, and that the preformistic, or inheritance, mechanism of germ cell establishment arose from convergent evolution. There are several key differences between these two mechanisms that may provide reasoning for the evolution of germ plasm inheritance. One difference is that typically inheritance occurs almost immediately during development (around the blastoderm stage) while induction typically does not occur until gastrulation. As germ cells are quiescent and therefore not dividing, they are not susceptible to mutation. Since the germ cell lineage is not established right away by induction, there is a higher chance for mutation to occur before the cells are specified. Mutation rate data is available that indicates a higher rate of germ line mutations in mice and humans, species which undergo induction, than in C. elegans and Drosophila melanogaster, species which undergo inheritance. A lower mutation rate would be selected for, which is one possible reason for the convergent evolution of the germ plasm. Elemp46 (talk) 23:28, 7 December 2018 (UTC)Reply
