A brother to sister breeding is true inbreeding.
It reduces the number of individuals who contribute to the litter's genetic make up by 50%.
It is a breeding strategy that has been used successfully in the past to imprint "type" or a certain look, etc. in a line. It brings the very best traits as well as the very worst traits to the phenotype where we can see them.
This is not a wise breeding strategy for the novice or small hobby breeder.
