Answer:
Polygenic inheritance occurs when one characteristic is controlled by two or more genes. Often the genes are large in quantity but small in effect. Some examples include height, skin color, eye color and weight.
- In polygenic inheritance the "dominant" capital genes are additive, each capital gene adding one unit of color to the genotype.With more capital genes, the phenotype (appearance) gets darker.

1.Heat and/or pressure 2. Weathering and erosion 3.melting. The heat and pressure will make the sedimentary rock into a metamorphic rock. The melting will make it into magma which will then cool and become igneous rock. The weathering and erosion will make the rock break down into small parts (sediments) which will stay like that for a long time and eventually become a sedimentary rock once again.
