The tilt of the earth's axis, which essentially "turns" certain parts of earth so that some parts receive more direct sunlight
When the effects of genes add up to make the phenotype, they are called additive genes.
Plants and fungi are usually filamentous to increase the surface area in which they uptake their food, and this is advantageous as they raise their surface area for sunlight in photosynthesis.
Conversely, animals are usually round to reduce surface area for loss of water and heat. Unlike plant and fungi, most of their food intake is through the mouth hence not affected by surface area.
Answer:
