ANSC 4395, Animal breeding and Genetics,
Exam 1 Questions with Verified Correct
Answers
Animal Breeding
scientific field that uses the principles of genetics to aid in the improvement of livestock
Robert Bakewell
Father of animal breeding
Shorthorns
one of the first organized breeds of livestock - 1580
Breed that was highly related to one or two bulls that were highly advertised:
Shorthorns
Sought individuals that would strengthen his heard. Leased out males to neighbors to
identify animals that produced superior offspring. Mated the best to the best with little
regard to ancestry.
Robert Bakewell
Gregor Mendel
studied genetics of the garden pea
established basic genetic principals that are still accepted today
Gregor Mendel
Population Genetics
, Branch of genetics which deals with the factors that affect the genetic structure of
populations.
Study of allele frequency distribution and change.
Statistic
estimate of a peramider
Dr. Sewell and Sir Ronald Fisher
pioneers of population genetics
Did the "paper work"
Dr. Jay Lush
"Father of Modern Animal Breeding"
Applied population genetics to animals
Heterosis
hybrid vigor
Established principles of selection, the use of inbreeding to conserve genes of some
individuals, and crossbreeding systems to take advantage of hybrid vigor.
Dr. Jay Lush
The primary goal for animal breeders:
identify animals with desirable genes and increase the frequency of those genes
Two fundamental questions
1. What is the best animal
2. How do you breed an animal so offspring will be the best or better than the parents
