How do the resulting cells at the end of meiosis compare to the original cell from the beginning of meiosis?

The daughter cells come together to make another identical parent cell.

Meiosis may be defined as the process of a cell division in which cell divides to multiply its number. The meiosis occurs in the germ cells or the sex cells of the organism.

The single cell divides into four different cells. The daughter cells has half the number of chromosomes as compared with the earlier parent cell. The DNA content is also half in the earlier cell and the daughter cell. The cells are genetically identical but contains the reduced number of chromosomes.

fertilization, pictured in figure 24.23a is the process in which gametes (an egg and sperm) fuse to form a zygote. the egg and sperm each contain one set of chromosomes. to ensure that the offspring has only one complete diploid set of chromosomes, only one sperm must fuse with one egg. in mammals, the egg is protected by a layer of extracellular matrix consisting mainly of glycoproteins called the zona pellucida. when a sperm binds to the zona pellucida, a series of biochemical events, called the acrosomal reactions, take place. in placental mammals, the acrosome contains digestive enzymes that initiate the degradation of the glycoprotein matrix protecting the egg and allowing the sperm plasma membrane to fuse with the egg plasma membrane, as illustrated in figure 24.23b. the fusion of these two membranes creates an opening through which the sperm nucleus is transferred into the ovum. the nuclear membranes of the egg and sperm break down and the two haploid genomes condense to form a diploid genome.
