Tissues and gene expressions

 this chemsavant nigger serious?
Single nucleotide polymorphisms are variations in the DNA, not gene expression.

Different tissues have different gene expression, not different DNA.
The only type of cells with different type of DNA would be germ cells and immune cells, which undergo recombination.

I mean sure, there could be random mutations that are introduced to various cells, but such changes would not vary by type of tissue nor would they be correlated at any particular point; that is, the cells in your lung may have more mutations due to exposure to carcinogen, but they're not going to share the same type of SNPs that is any different from your heart cells.

This guy throws around a lot of technical terms, like you'd expect from someone who's either taken some biology courses, or has attended a PhD program, but this kind of basic misunderstanding of molecular biology suggests that he probably got his PhD from a shit-tier nigger school.
