when compared to limiting DNA utilization
to only animals of a particular breed.
5.
Why are some traits influenced by
markers and others are not?
The genetic architectures of various traits are
different. Some are controlled by few genes with
large effects and some are controlled by many
small effects genes. In the current DNA profilers,
there are some markers with high correlations
with corresponding genes for some traits and low
correlations with others. That’s why we see the
different DNA added values for different traits. It is
hard to change the genetic architecture of a trait.
But, new DNA profilers or future technologies may

help to improve the value of DNA information for
such traits. Furthermore, some maternal traits,
like Maternal Calving Ease and Milk, are difficult
to predict with genomics because there are so
few females genotyped. Increasing the number
of cows and heifers genotyped will improve the
ability to use genomics to predict maternal traits.
6. Will genomic testing replace the need
to submit phenotype records?
No, reporting actual records is critical. The value of
genomic predictions increases as the amount of
phenotypic information increases. Furthermore,
at this point, animals cannot achieve high
accuracy with genomic data alone. High accuracy
