The dominant allele is expressed and the recessive allele is masked. This is an example of complete dominance. In heterozygous relationships where neither allele is dominant but both are completely expressed, the alleles are considered to be co-dominant. Co-dominance is exemplified in AB blood type inheritance.
Meaning: A low area (especially a marshy area between ridges) Classified under: Nouns denoting natural objects (not man-made) Hypernyms (swale is a kind of...): trough (a narrow depression (as in the earth or between ocean waves or in the ocean bed))
With a very gradual slope, a swale can move water and allow some infiltration into the ground. Using a swale for infiltration helps reduce the overall runoff from a property. A third type of swale works in conjunction with a perforated drainpipe to move water underground.
