Every somatic cell has the entire set of chromosomes. In a human, that would be 46: the 22 autosomes (chromosomes 1 through 22) x 2 copies (homologs) = 44 and then also 2 sex chromosomes (either XX or XY) = 46. Every germ cell (sperm or egg) has half of 46: either one of each of 22 autosomes + an X (oocyte) or one of each of the 22 autosomes + an X or a Y (sperm). In either case, germ cells in humans normally have 23 chromosomes.
I'm curious if you mean I look (check out the comparison at zimmer.csufresno.edu/~jross/images/joe-toby.png - might have to copy-paste the link for it to work properly), sound, or act similarly to Toby Flenderson (American version of The Office, played by Paul Lieberstein)? In other words: wondering if this is meant as a complement or insult. Regardless, if you learned something about the differences between sex chromosomes and autosomes, then I'm happy!
Lol what a ridiculous explanation. That is literally the definition of Petitio Principii - proposing a solution based on your assumption and using your solution to prove your point. @1:20. Little do you know that you actually proposed the logical solution @2:35 and then failed to use logical and instead, used circular reasoning and thus came to your same conclusion at a minute twenty in.. There is no evidence that the Y-chromosome is falling apart. Rather, they are just simply different. Always have been, always will be.
You are so calm and helpful thank you
thanks for this type of explanation i am bhavika from india my subject is biology and your explanation is very helpful for me
how the heck is he writing backwards better than i write forwards ?
Comprehendible explanation
where do you live
So that means
Autosomes = somatic cell = 46
and
Sex chromosomes = germline cell = 23
Is that true?

Joseph Ross thank you so much
It’s Toby from the office

The y chromosome emerged from the autosome that became the x. You can see this process occurring in multiple lineages where it has recently nucleated
