(c)[3]
Fig. 5.2 shows a horse, Equus caballus. Horses are diploid animals and reproduce sexually. Male and female horses make gametes, which fuse to produce genetically different offspring. Explain the need for a reduction division during meiosis in the production of gametes in animals such as horses.
