Final answer:
Haploid cells contain a single set of chromosomes and genetic information. Fruit fly gametes, for example, have a haploid number of 4, represented as n=4.
Step-by-step explanation:
Cells that contain only a single set of chromosomes and therefore a single set of genetic information are called haploid cells. Haploid cells are found in an organism's reproductive structures, such as the ovaries and testes.
Male gametes, like those of fruit flies, have a haploid number of 4 and can be written as n=4. Haploid cells contain a single set of chromosomes and genetic information. Fruit fly gametes, for example, have a haploid number of 4, represented as n=4.
