Kungoshandisa shanduro inogona kushanda. Mune dzimwe mhuri, nhaka yemaziso inotarisa inotevera maitiro akafanotaurwa asi mune dzimwe mhuri, haisi kuita seanonzwisisa kana kutevera mitemo ipi zvayo. Muzvinyorwa, izvi zvinonzi "polygenic." Polygenic zvinoreva kuti panogona kunge kune mazita emakemikari akaomeswa anobatanidzana anobatanidza kuumba mavara eziso.
Kunongotaura kuti ruvara runogona kunge rune ruvara rwebhuruu runoita kuti zvinyatsonzwisiswa, asi muenzaniso uyu hauna kunyanya kujeka nokuda kwezvinhu zvakasiyana-siyana zvinoonekwa muupenyu chaihwo.
Usaora mwoyo kana mageneti achifanotaura nezvekuchinja mumeso eruana wako.
