Records of other relatives in the pedigree (particularly sire and dam) genetic correlations of traits; as progeny records are added to a sire’s record, the accuracy of the epd increases and becomes more reliable. Breeders need to remember that epd values are not exact and actual progeny differences will vary from the predicted epd values.
There is a lack of information on beef cattle or dairy animals used for beef purposes. Even though the additive genetic variance is likely to be small, breed differences and heterosis estimates suggest that the total genetic variance is considerable.
Each herdbook registered animal receives an original and individual certificate of his/her ancestry, extending back three.

The pedigree gives you information about the genetic background of the animal. The genetic background can give you an indication of how well the animal will perform in the future, including milk production and genetic traits it can pass along to its progeny (or calves).
Pedigree chart the chart most people begin with is a pedigree chart. This chart begins with you and branches back in time, displaying the line of your direct ancestors. Most pedigree charts cover four generations, including space to include names plus dates and places of birth, marriage, and death for each individual.
A pedigree is used for different animals, such as humans, dogs, and horses. Often, it is used to look at the transmission of genetic disorders.

Autosomal recessive pedigrees can look differently based on the genotype of the parents. Here is an example pedigree: one trick for identifying a recessive trait is that if a trait skips a generation in a pedigree, it is often an autosomal recessive trait (although a trait can be autosomal recessive and not skip generations).
Genetic selection programs have transformed the dairy industry worldwide. The current dairy cow produces more than twice as much milk as the dairy cow of 50 years ago, and more than half of that improvement is due to genetic selection. The basic blocks for genetic improvement have been performance records and pedigree information.
