Marianna Haun
Pedigree Researcher, Writer for Associated Press, Author,
Owner, Breeder, Member of National Association of Turf Writers
Author of: The X Factor: The Relationship Between Inherited Heart
Size and Racing Performance
Background: A member of the National Turf Writers Association,
Marianna Haun has covered the racing industry for the past four years, first as
a staff writer for the Thoroughbred Times for two years, and now as a
free-lance writer for the Associated Press for the past two years, while
working on The X Factor project and book.
Haun has a long association with Secretariat. Like many people, she cried as
she watched him win the Belmont on television in 1973. She later photographed
him in 1987 and was on the farm the day he died in 1989. Her first story, "Great
Heart," which appeared in the Thoroughbred Times in April, 1993, led to the
quest to understand the meaning of Secretariat's enormous heart. Nearly a year
later, after months of intense pedigree research, she discovered a genetic link
from Secretariat's mighty heart to Eclipse's great heart through the mare
Pocahontas on the X chromosome trail. This link was called the X Factor.
It was this discovery that led to the on-going research to prove the
sex-linkage of the characteristic and to find the genetic marker.
The X Factor
The inheritance of the large heart through the female line on the X
chromosome and what it can mean in terms of racing performance and how to breed
and select for it.
Betting the Big Heart
How to bet Thoroughbreds based on the inside information of who possesses
the largest heart or biggest engine and where to look in the pedigree for it.
