   Y has about 100 protein-coding genes, which is a very small number for   
   its size in addition to it being a rather small chromosome. It mostly   
   consists of repetitive gene-poor sequence.

   "The human Y chromosome is composed of about 57 million base pairs of   
   DNA, making it similar in size to chromosome 19 and represents roughly   
   0.9% of the total DNA in a male cell. The human Y chromosome carries 693   
   genes, 106 of which are protein-coding.[56] However, some genes are   
   repeated, making the number of exclusive protein-coding genes just   
   42.[56] The Consensus Coding Sequence (CCDS) Project only classifies 63   
   out of 107 genes."
