Subject: number of avian genes
Hi,
A figure of 100,000 genes is usually assumed for mammalian genomes, but is
anyone aware of if the same number of genes is true for birds, eg. chicken?
If so, the fact that birds have only about one-third of the DNA content of
most mammals must imply that genes constitute a relatively higher share of
the genome in birds than in mammals (I recognise that this is so for the
chicken microchromosomes). In other words, if 5-10% of the human genome are
genes, the proportion in birds would be 15-30%. Is this correct?
Best wishes,
Hans
