The Single-Nucleotide Polymorphisms Found in the Human Population

Question

The single-nucleotide polymorphisms found in the human population
A)are important for genetic mapping because they represent mutations in genes important for human disease.
B)are rarely found among blood relatives.
C)can be linked into haplotype blocks.
D)arose mainly during the past 10,000 years.

Accepted Answer

Single-nucleotide polymorphisms (SNPs) can be linked into haplotype blocks due to their close proximity on a chromosome and patterns of inheritance. This allows for more efficient genetic mapping and identification of disease-causing genes. SNPs are not necessarily rare among blood relatives and their occurrence dates back much further than the past 10,000 years.
