How many chromosomes are in each somatic cell in humans how many are in a human gamete quizlet?

How many chromosomes do human somatic cells contain? 46 chromosomes composed of two sets of 23 chromosomes (2n; diploid). How many chromosomes do human gametes contain? One set of 23 chromosomes.

Do somatic cells have 23 chromosomes?

For example, in humans, somatic cells contain 46 chromosomes organized into 23 pairs. By contrast, gametes of diploid organisms contain only half as many chromosomes. In humans, this is 23 unpaired chromosomes.
