Jerry,
	Is it not that people go to the lake of fire because of sin?
And that the only way to not go to the lake of fire, is to repent and believe in Jesus, and his blood washes our sins away?
I do not remember any scriptures saying that the difference between the lake of fire, or not, is one's DNA.
Ethnicity is also not a factor, since Acts 10, the door to the Gentiles has been opened.
All have sinned, all are in danger of the lake of fire, but whosoever believes on Jesus will be saved.
Jesus did mention three exclusions, though:
1. Blasphemy against the Holy Ghost
2. Judas' betrayal of Jesus
3. Worshipping the beast, his image, taking his mark, name or number

The issue of blaspheming the Holy Ghost, betraying Jesus, or worshipping the beast, is an issue of the will, a choice.
It is a matter of the heart, not of the DNA.
