Guida verificata passo dopo passo1
Understand that a human somatic cell is a typical body cell, not a gamete (sperm or egg cell).
Recall that human somatic cells are diploid, meaning they contain two sets of chromosomes, one from each parent.
Know that the total number of chromosomes in a human somatic cell is 46.
Recognize that these 46 chromosomes are organized into 23 pairs of homologous chromosomes. Each pair consists of one chromosome from the mother and one from the father.
Conclude that the correct number of homologous chromosome pairs in a human somatic cell is 23 pairs.
