Explain how many phenotypes are there for a trait that has two alleles that are governed by incomplete dominance

The answer is 3 phenotypes. These are the homozygous dominant, homozygous recessive and heterozygous. In incomplete dominance, the dominant traits do not fully mask the recessive gene (note this is different from co-dominance). Example of incomplete dominance in humans is the alleles for straight and curly hair. Heterozygous for this trait is wavy hair due to incomplete dominance.

1. loamy sand is about 80% sand with 10% clay and defined mostly by sand particles with some clay to provide structure and fertility. the sand particles are easily visible and the soil holds structure but breaks apart easily.

2. scott sand can improve his soil quality by incorporating more silt and organic matter into the soil. peat moss and organic matter can also be incorporated.

as the gila monster consumes the eggs or young of the desert cottontail and gambel's quail, thus its main food supply is only accessible for a restricted time duration every year. however, for this, the gila monsters exhibit three adaptations, which elevate their survival rate in the desert condition.  

first, is that they possess huge bodies, and can consume greater concentrations of food during a small period. secondly, they require to feed infrequently as they can accumulate fat in their tails. ultimately, their rate of metabolism is very low, so that they can burn their reservoirs of fat gradually.
