(a)[2]
Structures A and B and the thallus of L. cruciata are haploid. Explain what is meant by haploid.
(b)[3]
Identify which of the structures A, B, C and D are: linked to sexual reproduction, made by mitosis, the site of meiosis. Each letter may be used once, more than once, or not at all.
(c)[3]
Fig. 5.2 shows a horse, Equus caballus. Horses are diploid animals that reproduce sexually. Male and female horses produce gametes, which fuse to form genetically different offspring. Explain the need for a reduction division during meiosis in the production of gametes in animals such as horses.
