Guida verificata passo dopo passo1
Understand that humans are diploid organisms, meaning their somatic cells contain two sets of chromosomes—one set inherited from each parent.
Recall that the total number of chromosomes in a typical human somatic cell is 46.
Since chromosomes come in pairs, divide the total number of chromosomes by 2 to find the number of pairs.
Use the formula: \(\text{Number of pairs} = \frac{\text{Total chromosomes}}{2}\).
Calculate \(\frac{46}{2}\) to determine the number of chromosome pairs in a typical human somatic cell.
