In genetics, incomplete dominance refers to an inheritance mode in which two gene variants (i.e., alleles) of the same <em>locus</em> combine in a way that neither allele dominates the other. This phenomenon is similar to codominance, but in this last case, both alleles are dominant. Incomplete dominance produces a new phenotypic trait resulting from the combination of both non-dominant alleles. An example of incomplete dominance includes the pink color of snapdragons resulting from the cross of red-flowered snapdragons with white-flowered snapdragons.
Your respiratory system takes in oxygen from the air. It also gets rid of carbon dioxide. Your digestive system absorbs water and nutrients from the food you eat. Your circulatory system carries oxygen, water, and nutrients to cells throughout your body.
Microbes were the first inhabitants of Earth. They are single-celled organisms, like bacteria, fungi, and protozoa. Microbes are still found just about everywhere today, thriving in boiling hot thermal springs Hope this Helps :D
