Applied Genetics Review

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 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

Which is an application of genetic engineering?

• destroying all bacteria

• creating synthetic insulin

• producing cells from nonliving material
