With recent strides in the uncovering of the genetic sequences of a long list of organisms, it is possible to create genetic variations from within the embryo or even at gamete level. In artificial selection, the variation of alleles is currently important, as is their heritability, although biotechnology may eventually render these criteria obsolete. A debilitating condition in man where the fight and flight reaction is replaced by temporary unconsciousness, goat breeding circles view this strange behavior in a more positive light. For thousands of years, humans have been influencing evolution, through changes If a species is produced that has beneficial traits over another species (for example a drought resistant plant), other species in the area could be outcompeted as they have not had their evolution accelerated at the same rate and their resources are taken from them. in the survival and reproductive success of individuals or groups best suited to their environment without human intervention. {{courseNav.course.mDynamicIntFields.lessonCount}} lessons Due to this lack of understanding, breeders can accidentally enhance genetically linked traits to the desirable trait, harming the organisms health.
