"People who like working with large quantities of data do well in this work," says Les Brinsfield. He is a pedigree analyst.

Following a horse's pedigree back for generations quickly increases the number of ancestors that need to be examined. Some arithmetic is required for this work. "You do need to be able to count," says Brinsfield.

"High school and college level math are important," adds Loren Bolinger, a pedigree analyst.

Currently, you're researching the pedigree of a potential stallion to see if his genetic qualities will match well with a brood mare you have at the stable. You begin by examining the stallion's pedigree chart.

In the first generation, a horse has 2 ancestors: a mother and a father.

In the second generation, a horse has 4 ancestors: 2 grandmothers and 2 grandfathers.

  • How many ancestors are in the stallion's sixth generation?
  • How about the seventh?
