Part C
Which of these cells is (are) haploid?

The process of meiosis. Initially, chromosomes are scattered all over the cell. This stage is labeled A. During interphase, they become replicated and arranged in pairs of homologous chromosomes. This stage is labeled B. During meiosis 1, the cell divides into 2 and each cell has 1 chromosome. One of these daughter cells is labeled C. During meiosis 2, cells from meiosis 1 divide into 2 once again. The resulting cells all have 1 chromatid and one of such cells is labeled D.

Answer 1

Sure! Here are the answers to your questions:

Part A
Human gametes are produced by meiosis.

Part B
Normal human gametes carry 23 chromosomes.

Part C
The cells that are haploid are C and D. (After meiosis I, the daughter cells are haploid, and after meiosis II, the resulting cells are still haploid.)

Part D
A diploid organism whose somatic (nonsex) cells each contain 32 chromosomes produces gametes containing 16 chromosomes. (Gametes are haploid, so they will have half the number of chromosomes of the diploid organism.)
