The factor that will cause the next generation of cows to receive the trait for producing large quantities of milk is information in the cows chromosomes.
This information is encoded in the DNA and determines the genetic traits that offspring inherit from their parents. Selective breeding aims to enhance certain traits, such as milk production, by choosing parent cows with desirable genetic characteristics for reproduction. The other options (nutrients, minerals, and electric impulses) may affect the health or performance of individual cows but do not directly pass on traits to the next generation.
