bapak X anak / mak X anak / adik beradik x sama sendiri... sama je = chances 25% (tertinggi) dari segi traits & risks...
tp aku quote dr Wiki, "Inbreeding is breeding between close relatives, whether plant or animal. If practiced repeatedly, it can lead to exposure of recessive, deleterious (harmful to health or well-being) traits. This generally leads to a decreased fitness of a population"...
Inbreeding may result in a far higher phenotypic expression of deleteriousfirst-generation inbred individuals are more likely to show physical and health defects, including: (memudaratkan/membahayakan) recessive genes within a population than would normally be expected. As a result,
- Reduced fertility both in litter size and sperm viability
- Increased genetic disorders
- Fluctuating facial asymmetry
- Lower birth rate
- Higher infant mortality
- Slower growth rate
- Smaller adult size
- Loss of immune system function

Pandai pun. Kalau nak ternak haiwan kena paham biologi bukan takat pandai reka & buat reban saja.
Bukan orang puteh saja tau pasal inbreeding, orang arab pun tau pesal tu ada larangan agama kawin adik beradik.
Inbreeding boleh dielakkan kalau population/stock besar dan kawasan roaming range jugak besar. Kalau stock kecik, boleh hantar ayam/itik/arnab ke ladang/rumah orang lain untuk dikahwinkan macam ayah mak buat pada lembu atau kerbau dulu.
yup2 mmg kena buat pon...tp br jumpa sowang je yg ada baka mcm yg ada kat rumah ni...penghulu tu.
