| traits which # have a specific range | |
| of trait which lies in between # | |
| two extreme such trait are termed # as | |
| Quantitative traits . Qualitative traits which | |
| is controlled # by a single gene and do | |
| not have many differences among each other | |
| called qualitative traits. Qualitative traits does | |
| # not lies in a Specific range in | |
| b/w two extreme # # as they can easily be | |
| distinguished form one another . e.g Blood group . | |
