Answer the following question given this paragraph: 

Each human somatic cell (a body cell, or every cell other than a gamete) normally has two sets of chromosomes, one set inherited from each parent. These cells are said to have a diploid number of chromosomes. Each set contains 23 chromosomes, for a total of 46 chromosomes. Each chromosome differs in size, from about 250 million nucleotide pairs on the largest chromosome (chromosome #1) to less than 50 million nucleotide pairs on chromosome #22. Each chromosome contains a specific set of genes, as well as regulatory elements and other nucleotide sequences, making each chromosome essential to survival.


Q: How many sets of chromosomes does each somatic cell have?


A:
two
