Questão
what are single nucleotide polymorphisms?
Responda
positions in a gene where there is only one base
positions in a gene where more than one bases are present
a specific position on the chromosome
different forms of the same gene that occupy the same locus

Responda
they change shape, become trapped in the capillaries, and reduce blood flow
the change shape, become trapped in the arteries, and reduce blood pressure
they are heritable factors that consist of the length of DNA and influence a specific characteristic
they are specific positions on a chromosome
