White Silkie rooster Black Silkie rooster. The chicken breeds Silkie and Ayam Cemani commonly exhibit this trait. Ayam Cemani is an uncommon and relatively modern breed of chicken from Indonesia. They have a dominant gene that causes hyperpigmentation (Fibromelanosis), making the chicken entirely black; including feathers, beak, and internal ...
Gyotaku (魚拓, from gyo "fish" + taku "stone impression", fish print(ing)) is the traditional Japanese method of printing fish, a practice which dates back to the mid-1800s. This form of nature printing , where ink is applied to a fish which is then pressed onto paper, was used by fishermen to record their catches, but has also become an art ...
Autosomal dominant and autosomal recessive inheritance, the two most common Mendelian inheritance patterns. An autosome is any chromosome other than a sex chromosome.. In genetics, dominance is the phenomenon of one variant of a gene on a chromosome masking or overriding the effect of a different variant of the same gene on the other copy of the chromosome.
Inherited imprinted genes of offspring are believed to be monoallelic expressions. A single locus will entirely produce one's phenotype although two alleles are inherited. This genotype class is called parental imprinting, as well as dominant imprinting. [68] Phenotypic patterns are variant to possible expressions from paternal and maternal ...
A phenotypic trait is an obvious, observable, and measurable characteristic of an organism; it is the expression of genes in an observable way. An example of a phenotypic trait is a specific hair color or eye color. Underlying genes, that make up the genotype, determine the hair color, but the hair color observed is the phenotype.

The black and white snapper has a wide Indo-Pacific range. It occurs along the eastern coastline of Africa from the Red Sea south as far as South Africa, the Seychelles, islands in the Mozambique Channel, Madagascar and western Mascarenes, east to the Maldives, Laccadives, the Chagos Islands, Cocos (Keeling) Islands and Christmas Island and Sri Lanka.
The hemoglobin protein is made of two subunits (alpha and beta). In 15 of the 16 icefish species, the beta subunit gene has been completely deleted and the alpha subunit gene has been partially deleted. [13] One icefish species, Neopagetopsis ionah, has a more complete hemoglobin beta subunit, but a still nonfunctional, hemoglobin gene. [14]
