Which of the following is true of artificial insemination?
It is only used in cattle breeding programs
It involves natural mating between a selected male and female
It can increase the genetic diversity of a herd
It allows breeders to control the genetics of the offspring produced
It allows breeders to control the genetics of the offspring produced. Artificial insemination is a technique in which sperm from a selected male is introduced into the reproductive tract of a female, without natural mating. This allows breeders to control the genetics of the offspring produced and increase the chances of producing desirable traits, such as increased milk production or improved meat quality. It is not limited to cattle breeding programs, and in fact, it is used in a wide range of animal breeding programs. However, it does not increase the genetic diversity of the herd, as it relies on the selection of specific individuals with desirable traits. Hence option 4 is the correct answer.
