What is Genetic variation?
The difference in the DNA among members of a species.
Are features that are visible when you look at an animal. E.g. Aberdeen angus cattle are polled (hornless)
The process by which humans breed plants or animals with desirable traits and concentrate on those desirable traits in the offspring
Involves the manipulation of hereditary characteristics in order to improve or produce desirable characteristics in offspring.
What are Physical traits ?

What is performance testing?
The evaluation of a bull’s performance by comparing its weight gain and FCR with other bulls kept under similar feed and housing conditions.
The evaluation of the performance of a bull’s offspring compared to other bulls’ offspring under similar feed and housing conditions.
Study of an animals DNA
Is the process of identifying differences in the genetic make-up (genotype) of an animal by examining the animals DNA sequence and comparing to other animals
What is genomics?
The evaluation of a bull’s performance by comparing its weight gain and FCR with other bulls kept under similar feed and housing conditions.
The evaluation of the performance of a bull’s offspring compared to other bulls’ offspring under similar feed and housing conditions.
Study of an animals DNA
Is the process of identifying differences in the genetic make-up (genotype) of an animal by examining the animals DNA sequence and comparing to other animals
What is genotyping?
The evaluation of a bull’s performance by comparing its weight gain and FCR with other bulls kept under similar feed and housing conditions.
The evaluation of the performance of a bull’s offspring compared to other bulls’ offspring under similar feed and housing conditions.
Study of an animals DNA
Is the process of identifying differences in the genetic make-up (genotype) of an animal by examining the animals DNA sequence and comparing to other animals
What is progeny testing?
The evaluation of a bull’s performance by comparing its weight gain and FCR with other bulls kept under similar feed and housing conditions.
The evaluation of the performance of a bull’s offspring compared to other bulls’ offspring under similar feed and housing conditions.
Study of an animals DNA

What is natural selection?
Genes that can cause the death of an organism
Can identify potentially genetically superior animals at a very young age by examining the DNA of the young animal and comparing it to the genotype of proven animals
Is an animal that has been identified as a genetically superior animal based on both performance and progeny testing.
Is the process whereby organisms better adapted to their environment tend to survive and produce more offspring.
What is a lethal gene?
Genes that can cause the death of an organism
Can identify potentially genetically superior animals at a very young age by examining the DNA of the young animal and comparing it to the genotype of proven animals
Is an animal that has been identified as a genetically superior animal based on both performance and progeny testing.
Is the process whereby organisms better adapted to their environment tend to survive and produce more offspring.
What is a proven animal?
Genes that can cause the death of an organism
Can identify potentially genetically superior animals at a very young age by examining the DNA of the young animal and comparing it to the genotype of proven animals
Is an animal that has been identified as a genetically superior animal based on both performance and progeny testing.
Is the process whereby organisms better adapted to their environment tend to survive and produce more offspring.

What is gene editing?
Produces genetically identical individuals.
Altering an organisms DNA for the purpose of improvement or to correct a defect in the organism.
Is an artificial substance (medium) containing nutrients and used to maintain the growth of cells.
Allows scientists to add, delete, replace a base in the genome thereby changing the sequence of the genetic code.
What is genetic modification (GM)?
Produces genetically identical individuals.
Altering an organisms DNA for the purpose of improvement or to correct a defect in the organism.
Is an artificial substance (medium) containing nutrients and used to maintain the growth of cells.
Allows scientists to add, delete, replace a base in the genome thereby changing the sequence of the genetic code.
What is cloning?
Produces genetically identical individuals.
Altering an organisms DNA for the purpose of improvement or to correct a defect in the organism.
Is an artificial substance (medium) containing nutrients and used to maintain the growth of cells.
Allows scientists to add, delete, replace a base in the genome thereby changing the sequence of the genetic code.
What is a culture?
Produces genetically identical individuals.
Altering an organisms DNA for the purpose of improvement or to correct a defect in the organism.
Is an artificial substance (medium) containing nutrients and used to maintain the growth of cells.
Allows scientists to add, delete, replace a base in the genome thereby changing the sequence of the genetic code.
