The number of genes in the human genome has been reduced recently to around 19,000. It is estimated now that 81% of all genes in bacteria may have been involved in HGT at some point. At this point it is controversial just how much of the human genome has been involved in HGT. It is much smaller for sure but still a certain number is not available as far as I know of.There are 30,000 genes in the human genome. 300 genes acquired by HGT would be 1% of the total genome, with 99% due to vertical inheritance.
