When neither gene in a genotype pair is dominant and neither gene is recessive, the genes are said to be multiple alleles incomplete dominant alleles incomplete alleles

The correct answer for the blank is- incomplete dominant alleles .

Incomplete dominance (also known as partial dominance) occurs when a dominant form of a gene does not completely masks the expression of another gene variant ( that is a recessive allele).

In this inheritance, a genotype with heterozygote condition ( with neither a dominant allele nor a recessive allele) results in an intermediate phenotype ( which depicts a blend of phenotypes that lies between the phenotypes of two homozygous parents).

For example- When a snapdragon red flower is crossed with a white flower, it produces pink snapdragon, representing 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.

i think that is new experiments yield untrustworthy data and should be carefully considered, because you don't know what will happen with the experiments.
