What properties of DNA and Chromosones do birds have? How many chromosones do males and females have? Are the nucleotides the same (CGAT)?

There are a lot of different kinds of birds. Maybe the DNA varies a lot among them, so I want to specify: Fowls (gamefowl/landfowl/waterfowl).

    $\begingroup$ Yes. Birds do have DNA. I don't understand what you mean by the type. If you mean by geometry, I suppose they should be having all 3 A, B, Z- DNA. Chromosome number varies with species. 'Birds' is a class of animals with many many species.. so ya - you can't generalize. Sex determination also varies. Since you ask for the fowl - males are homogametic - ZZ and females are heterogametic with ZW. So in a way, it is opposite to that in humans. I don't understand why you expect birds to be that different $\endgroup$ – Polisetty Oct 29 '16 at 4:36

    $\begingroup$ -1, the most basic search will confirm that birds, and indeed all life above eukaryotes, have genomes encoded by DNA. $\endgroup$ – Michael_A Oct 29 '16 at 5:35
  • $\begingroup$ @Michael_A Which is why I asked "what kind of DNA"---and specified the properties I'm interested in, instead of asking "do they have DNA at all?". $\endgroup$ – DrZ214 Oct 29 '16 at 8:07
  • $\begingroup$ Then, what are the 'kinds' of DNA u r looking for? $\endgroup$ – Polisetty Oct 29 '16 at 9:22

    $\begingroup$ @DrZ214, My comment is specific to these two questions. Is it really DNA, or rather RNA, or something else? Are the nucleotides the same (CGAT)? You have posed 4 questions which confuses the issue. Polisetty's question is a good one, I also don't understand what you mean by kind of DNA. $\endgroup$ – Michael_A Oct 29 '16 at 9:46

The class "Aves" fall under the kingdom Animalia. Therefore, they are multicellular eukaryotic organisms. Being eukaryotes, their genetic information is encoded in linear double stranded DNA.

What is their chromosome number? Fowls (gallus Domesticus) have approximately 36. It varies from bird species to bird species as much as it does from humans (46) to gorrilas (48). Chickens have 78, and so on.

The genetic code is universal. It is used by virtually all known organisms, save some very specific outliers.
