a cell with one copy of each chromosome (n)
A
meiosis
B
chromosome
C
diploid
D
haploid
Explanation: 

Detailed explanation-1: -Haploid describes a cell that contains a single set of chromosomes. The term haploid can also refer to the number of chromosomes in egg or sperm cells, which are also called gametes. In humans, gametes are haploid cells that contain 23 chromosomes, each of which a one of a chromosome pair that exists in diplod cells.

Detailed explanation-2: -During fertilisation, an egg and sperm (gametes) combine to form a cell that contains a complete complement of DNA. In humans, these gametes are haploid as they have one copy of each chromosome, contributed from each parent.

Detailed explanation-3: -Most human cells are diploid, and only the gametes (i.e., the sperm and egg cells) are haploid. Haploid cells contain half the number of chromosomes as diploid cells. A human diploid cell contains a total of 46 chromosomes (2n = 46), so a haploid cell will contain 23 chromosomes (n = 23).

Detailed explanation-4: -Final answer: The egg cell and the antipodal cells have a haploid number of chromosomes.
