Trisomy is having 3 chromosomes but then what is partial trisomy ?. I was reading about Patau syndrome and it is called trisomy 13 ( because instead of usual 2 chromosomes,it has 3 chromosomes). it was also wriiten that 20% cases are PARTIAL TRISOMIC...what is the meaning of partial trisomic?

    $\begingroup$ I assume you checked Google first? The first result looks like it covers this (rarediseases.org/rare-diseases/chromosome-6-partial-trisomy-6q) - are you asking for further explanation of some aspect of this? $\endgroup$

1 Answer 1


Any organism with a partial polyploidy has got some tissues with a different number of chromosome set, unlike the rest of cell tissues. These situations are often consequences of meiosis error and are more common in plants than in any other organism.

  • $\begingroup$ I think the OP's question is "What does it tell about the genetics of an individual if this individual has partial trisomy?". I don't think the question was "What are the health consequences of partial trisomy?" nor "How does partial trisomy comes to exist?" $\endgroup$

  • $\begingroup$ Partial trisomy is just an example of a partial polyploidy. So actually I think my answer is short but straight to the point. $\endgroup$
