I had wondered this for a while, and finally tried to look it up today, but I couldn't get a definitive answer... The first site I went to said they have 14 chromosomes, the second site said 24, the third said 26, and so did the fourth, then the fifth said 14 again! So here I am, wondering how many chromosomes budgies really have.
I also stumbled upon that site, and an article by Ghalib Al-Nasser as well, which also said 26. It just makes me wonder why other sites say different numbers. Where are they getting their information from?
I am now wanting to know for sure - going to call the Avian vet on Monday!!
Good plan, or ask a avian vet lab technician since they're the ones who do DNA profiling and gender determination. Let me know what you find out!
I've been planning on karyotyping my budgies genes (one way to find out gender), but that's hard to do when you don't know how many chromosomes budgies have!
"Different literary sources at different times have stated that the budgerigar has somewhere between 13 and 60 pairs of chromosomes in each cell." According to Ken Yorke, no one really seems to know how many chromosomes budgies have!
