Energy in the depositional environment: The first key to the identification of sedimentary facies and environments is the relationship between energy and clast size. Generally, the higher the energy (that is, the faster the wind or water is moving) the larger the grains that can be kept in suspension.
pig porphyria. an erythropoietic porphyria, similar to bovine congenital erythropoietic porphoryia, but inherited as a dominant trait. Discoloration of the teeth, bones and tissues occurs, but not of the urine, except in severely affected cases.Photosensitization is not a feature. The enzymatic defect is unknown.nherited as an autosomal dominant trait; affected cats have discolored teeth, urine and tissues, severe anemia and photosensitivity associated with a deficiency of uroporphyrinogen III cosynthetase. inherited porphyria. the disease is inherited in cattle and swine and is similar to erythropoietic porphyria of humans.
Dominance in genetics is a relationship between alleles of one gene, in which the effect on phenotype of one allele masks the contribution of a second allele at the same locus.The first allele is dominant and the second allele is recessive.For genes on an autosome (any chromosome other than a sex chromosome), the alleles and their associated traits are autosomal dominant or autosomal recessive. Dominance is a key concept in Mendelian inheritance and classical genetics.t is a relationship between alleles; one allele can be dominant over a second allele, recessive to a third allele, and codominant to a fourth. Also, an allele may be dominant for a particular aspect of phenotype but not for other aspects influenced by the same gene.
