What is a phenotype in pig?
A phenotype is a set of observable characteristics of a pig resulting from the interaction of its genotype with the environment. Genetic markers and equations are of little value without accurate phenotypes.
What are pigs inherited traits?
Examples of traits observed include color, litter birth weight, loin eye area, and backfat thickness. Some of these traits have a higher heritability, meaning the differences we observe among pigs can be attributed more to the pigs’ genetics than their environment.
What are the crossbreeds developed with our native pigs?
Another is the black Diani, a cross between the native pig in Batangas and the Berkshire pig. The black Ilocos strain is a cross between the native pig and the Berkshire or Poland China breeds, while the Koronadal strain of Cotabato is an intermediate breed between the lard and bacon types.

What is native pig production?
A native pig is a product of indiscriminate crossbreeding between domesticated wild pigs and introduced breeds of pigs. After a long process of natural selection, it has evolved into a group that is able to survive and reproduce under natural environments even with minimal human interventions.
What is dominant and recessive traits in swine?
A pig with a dominant gene will display that particular trait; one with a recessive gene may display the trait or be a carrier; and one with an X-linked gene will be a carrier or affected depending upon which parent is the carrier or whether both parents are carriers.
What are the characteristics of Philippine Native pig?
What are the common breeds of swine found in the Philippines and their distinctive characteristics?

What are the advantages of raising native swine?
An advantage of native pig farming is the low capital requirement. They are easy to raise and are highly adaptable to local conditions. In addition, native pigs can survive by making use of local feed sources and simple management practices.
