Humans are diploid organisms, and their gametes contain 23 chromosomes. Fill in the blank in each sentence using the terms. Each
USPshnik [31]

Answer:

2n, n, diploid

Explanation:

<em>When the somatic cells of human are in interphase, the ploidy level is denoted as </em><em>2n (diploid)</em><em>. The ploidy level of the human's gametes is denoted as </em><em>n (haploid)</em><em>. The 2n number of a human is </em><em>diploid</em><em>.</em>

Somatic cells are also known as vegetative cells and all somatic cells of humans have diploid number of chromosomes. At interphase, the number of chromosome remains diploid (2n) but the amount to DNA is doubled at the synthesis phase of the interphase.

Human gametes are formed through meiosis - the division of sex cells in the human body. Meiosis results in the halving of number of chromosomes of cells. Hence, all human gametes contain half the number (n = 23) of chromosome of vegetative cells.

Humans are diploid organisms with diploid (2n = 46) number of chromosomes in their vegetative cells.
