The main biological problem with inbreeding is the loss of diversity of the alleles in the population. The negative effects described in various other answers, such as deformities, are the result of lack of selection in the inbreeding process. The various "breeds" of purebred agricultural and other domestic animals are the result of inbreeding combined with a rigid selection for the characteristics desirable in the breed. The end result being an animal that more closely meets our desires or needs, but that has less genetic diversity in the breed for future selective breeding for other traits.

The main problem with inbreeding has to do with allele frequency. In a healthy population with very little or no inbreeding, you tend to find several alleles for many genes. However, when a population inbreeds, the number of alleles formany of the genes gradually drops to 1. This reduces allele frequency and in effect renders a population susceptible to disease.
Just say NO to inbreeding!!!!!!! Word'em up!!

Children are usually born with birth defects. This is why one needs a blood test in USA before aquiring marriage license and so forth.
I have a good joke regarding this subject:
A mother arrives home and finds her daughter crying her eyes out. "Mom, mom cries the girl there isn't going to be a wedding, Daddy told me that he had an affair with Tommy's mother (the boy next door) and that he is my half brother therefore we cannot get married."
There,there, said the mother there is nothing to worry about because "Daddy" isn't your biological father either.

the offspring are most likely deformed in some way due to multiple recessive genes and a lack in the variety of dna.

A recessive gene for a disease becomes dominant since both parents potentially could be carriers.

genetic abnormalities are passed on through both parents and emphasized.eventually the offspring would be unable to function.
