Jiffy Peat Pellets. Our customers prefer Jiffy Pellets for seed starting. The outer net of the pellets is decomposable, which means it will degrade under compost conditions (speed and degree will vary with conditions), while retaining its strength through the critical seeding and transplanting stages.ur customers prefer Jiffy Pellets for seed starting.

Heterochromia means different (hetero-) colors (-chromia).. Usually the term is used to describe the condition where a person has different colored eyes â one blue eye and one green eye, for example. Other terms to describe different colored eyes are heterochromia iridis and heterochromia iridum. Iridis and iridum refer to the iris of the eye. The iris is the thin, circular structure that surrounds the pupil and contains the pigment melanin, which gives our eyes their distinctive color.
Humans and other animals have many phenotypic variations in eye color. The genetics of eye color are complicated, and color is determined by multiple genes. So far, as many as 15 genes have been associated with eye color inheritance.Some of the eye-color genes include OCA2 and HERC2. The earlier belief that blue eye color is a simple recessive trait has been shown to be incorrect.ome eyes have a dark ring around the iris, called a limbal ring. Eye color in non-human animals is regulated differently. For example, instead of blue as in humans, autosomal recessive eye color in the skink species Corucia zebrata is black, and the autosomal dominant color is yellow-green.
