Final answer:
After meiosis I, there are two haploid daughter cells. These cells further divide during meiosis II to form a total of four unique haploid daughter cells, each with half the number of chromosomes of the original diploid cell.
Step-by-step explanation:
The number of daughter cells after meiosis I is two. Meiosis is a two-step process that includes meiosis I and meiosis II. During meiosis I, one diploid parent cell undergoes replication and division to produce two haploid daughter cells. These cells are not genetically identical to each other nor to the parent cell because crossover and recombination events during meiosis I introduce genetic diversity.
After meiosis I, each of the two haploid cells divides once more during meiosis II, similar to mitosis, to separate the sister chromatids. This second division does not replicate the DNA and results in four unique haploid daughter cells, each containing half the number of chromosomes as the original diploid parent cell. For example, in human cells where the diploid number is 46 chromosomes (23 pairs), the cells produced by meiosis will each have 23 chromosomes, ready to form gametes.
