Animal Genetics

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 ?

• 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 is Applied genetics?

• 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 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.

• 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.
