I understand, I will be very careful before I use your name again.
Thank You for being gracious about it.

You can't shake hands with a clenched fist.
I think we are drawn to dogs because they are the uninhibited creatures we might be if we weren't certain we knew better.
It is much easier to show compassions to animals. They are never wicked.
Be polite, be professional, but have a plant to kill everyone you meet.
If I had no sense of humor, I would long ago have committed suicide.
Dogs are better than human beings because they know but do not tell.
The weak can never forgive. Forgiveness is the attribute of the strong.
People don't know how chickens can turn on you, but they can -- just like mad dogs.

I am not familiar with the presentation of c+?
CC - color
Cc-color
cc-white
c+=?
Anoter thing the dispersing level of the melanin is dependent on another gene, the E (extention ) gene.
Tara thanks for reminding me why I hate genetics so much!![]()
It is a mutation that happened in the middle of the embryo development , whas it black also in its body?
A genetic chimerism or chimera (also spelled chimaera) is a single organism composed of cells from different zygotes. This can result in male and female organs, two blood types, or subtle variations in form. Animal chimeras are produced by the merger of multiple fertilized eggs. In plant chimeras, however, the distinct types of tissue may originate from the same zygote, and the difference is often due to mutation during ordinary cell division. Normally, genetic chimerism is not visible on casual inspection; however, it has been detected in the course of proving parentage.
Another way that chimerism can occur in animals is by organ transplantation, giving one individual tissues that developed from two genomes. For example, a bone marrow transplant can change someone's blood type.
Animals
An animal chimera is a single organism that is composed of two or more different populations of genetically distinct cells that originated from different zygotes involved in sexual reproduction. If the different cells have emerged from the same zygote, the organism is called a mosaic. Chimeras are formed from at least four parent cells (two fertilised eggs or early embryos fused together). Each population of cells keeps its own character and the resulting organism is a mixture of tissues. There are some reports of human chimerism.
This condition is either inherited or it is acquired through the infusion of allogeneic hematopoietic cells during transplantation or transfusion. In nonidentical twins, chimerism occurs by means of blood-vessel anastomoses. The likelihood of offspring being a chimera is increased if it is created via in vitro fertilisation. Chimeras can often breed, but the fertility and type of offspring depends on which cell line gave rise to the ovaries or testes; varying degrees of intersex differences may result if one set of cells is genetically female and another genetically male.
Colour-sided is a colour pattern of domesticated cattle. It is sometimes called lineback
It consists of a dark body colour, with white finching along the spine, white under the belly, and often white also over the tail, head and legs. The ears, nose and feet are generally dark. The pattern may occur in many breeds, but some breeds are consistently colour-sided, including English Longhorn cattle, Irish Moiled cattle, Randall cattle, Riggit Galloway cattle and Lineback cattle. The dark colour may be any solid colour such as black, red or brindle.
An extreme pale form of the colour-sided pattern is where the darker colour is restricted to the ears, nose and feet, leaving most of the animal white. This is found for example in White Park, British White, and some Irish Moiled cattle.
Coat color was very variable in early domesticated stocks. In many breeds, color became one of the traits under intense selection and ultimately color became part of the identity of many breeds. However in some older breeds, such as Highland and Longhorn, color has remained varied. The painting above hangs in the Department of Animal and Poultry Science in the Agriculture Building at the University of Saskatchewan in Saskatoon. We are proud to display this important documentation of our cattle heritage. It is entitled "Highland Cattle - By the Sea" and was painted by William Smellie Watson of Scotland in 1872, before the Highland cattle registry began. It was donated by Al Ewen, who retired as Head of the Department of Animal Husbandry in 1952 when he returned to Aberdeernshire, Scotland.
Tara read this, this was a classic in basic genetics.

And this shows that sometimes it needs to be COLD to have a pigment......
Markings
The Himalayan rabbit is well known for its markings, which are similar to the Himalayan cats'. They have dark ears, front feet (socks), hind feet (boots), a dark tail, and a dark spot on nose (egg). The markings change with age and environment. The colder weather may darken markings, enlarge markings,
The Himalayan (a.k.a. Himalayan Persian, or Colourpoint Persian as it is commonly referred to in Europe), is a breed or sub-breed of long-haired cat identical in type to the Persian, with the exception of its blue eyes and its point colouration, which were derived from crossing the Persian with the Siamese.
