Guida verificata passo dopo passo1
Understand that human somatic cells are diploid, meaning they contain two sets of chromosomes—one set inherited from each parent.
Recall that the haploid number (n) for humans is 23, which represents the number of chromosomes in gametes (sperm or egg cells).
Since somatic cells are diploid, calculate the total number of chromosomes by multiplying the haploid number by 2: \(2 \times 23\).
This calculation gives the total number of chromosomes present in a typical human somatic cell.
Recognize that the correct answer corresponds to this total number of chromosomes.
