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.

Answer:
3.Flood
Explanation:
Flood is the catastrophic event which is the main cause of the most weathering and erosion in the least amount of time in this ecoregion because there is no vegetation present in this region and the soil is vulnerable for erosion. Flash-flooding and rapid runoff are agents of erosion in the Trans-Pecos ecoregion of Texas whenever the rainfall occurs. Vegetative is very important for preventing soil erosion so the people of this region has to stop overgrazing in this area in order to avoid more erosion of the soil.
