We want to breed for larger adult weights for pigs using individual phenotype, in which the population means is 500 lbs and the standard deviation of phenotype is known to be 50 lbs. The adult weight heritability is 0.45. Pig A weighs 475 lbs. Thus, we want to breed the pigs utilizing genomic information, and the selection accuracy for the new criterion is 0.65. Based on this given information, what is the genetic gain per generation assuming the selection differential is 100 lbs?

Genetic Evolution

Sexual reproduction produces distinct population variations. Heredity determines the traits and qualities to be passed down to the progeny. Over time, this variation within-species is also affected by the process of human evolution. The study of how genetic variation leads to evolutionary changes is known as genetic evolution. If a trait helps an organism to survive and reproduce, it is more likely to be passed down the generations. It is rare that such traits result in a completely distinct set of traits in descendants than the ancestral population; this can result in the emergence of a new species.
