Redhead baby question.?

Question

Im russian, chinese and mongolian descent. My grandma was a natural redhead. None of my dad's brothers/sisters have red hair. My mother has freckles but no red hair.

This girl is irish, peruto rican, italian, german. She said one of her grandma had natural red hair.

The chance of getting red hair baby with hers and my genes are prolly 25%? Ty

Answer 1

Perhaps, although most Chinese and Mongolians probably don't pass along the gene for red hair, it's not unheard of for Northern Italians, Puerto Ricans, Germans, and, of course, Irish to have red hair.  If you grandmother has red hair and your girl's grandmother has red hair, you stand at  good chance of producing a red-haired child, although perhaps not 25 percent.

My maternal grandmother had red hair (her mother was a Scot and her father, Irish). Two of her five children had red hair, and three of her nine grandchildren did.  My brother and his wife (both with blond hair) had four children--one of them has red hair; the other three are blondes.  (I'm primarily of Scottish, Irish, and English descent, so perhaps my chances of producing a red-haired child are a little higher than yours.)

Answer 2

Red hair  is characterized by high levels of the reddish pigment pheomelanin and relatively low levels of the dark pigment eumelanin. Approximately 1% to 2% of the human population has red hair. It occurs more frequently (between 2% and 6% of the population) in northern and western Europeans, and their descendants, and at lower frequencies throughout other parts of Europe, Asia and Africa.

    Red hair appears in people with two copies of a recessive gene on chromosome 16 which causes a change in the MC1R protein. It is associated with fair skin color, freckles, and sensitivity to ultraviolet light, as the mutated MC1R protein is found in the skin and eyes instead of the darker melanin.

     The Kyrgyz people of central Asia once had predominantly red hair. Some today still retain this trait. Genghis Khan, emperor of the Mongol Empire,  traditionally and by some scattered accounts is said to have had red hair. Red hair has also been found in Asia, notably among the Tocharians who occupied the northwesternmost province of what is modern-day China. The 2nd millennium BC caucasian Tarim mummies in China were found with red and blonde hair and most likely were of European origin. Paintings from the 9th and 10th centuries show red-headed, blue-eyed Central Asians (Tocharian?) and East-Asian Buddhist monks from Bezaklik, in the Eastern Tarim Basin,  located in the Xinjiang Uyghur Autonomous Region in China's far west. It occupies an area of more than 400,000 km².

    Today, red hair is most commonly found at the western fringes of Europe. It is associated particularly with those in Scotland, Ireland , Wales, and England. This matches the movement of the Celts and Picts as they were pushed westward and northward in Britain and Ireland during the Roman conquest of Britain, as well as the pattern of Viking settlement in the north of England. Scotland has the highest proportion of redheads, as 13 percent of the population has red hair and approximately 40 percent carries the recessive redhead gene.  Ireland has the second highest percentage; as many as 10 percent of the Irish population have ginger, auburn (red-brown) or strawberry blond hair. It is thought that up to 46 percent of the Irish population carries the recessive redhead gene. Red hair reaches frequencies of up to 10 percent in Wales.

    In the United States, anywhere from two to six percent of the population is estimated to have red hair. This would give the U.S. the largest population of redheads in the world, at 6 to 18 million, compared to approximately 650,000 in Scotland and 420,000 in Ireland.

     In Asia, darker or mixed tinges of red hair can be found sporadically from Northern India, northern Middle East (such as Lebanon, Iran, Syria) and Pakistan, and in rare instances in Japan  and the South Pacific. In Australia red hair makes up 3% to 5% this is due to the extensive amount of Australians originating from the British Isles.

    Red hair is caused by a recessive gene that can skip generations before reappearing, and it is also relatively rare. But it is not likely to disappear any time in the foreseeable future. (NOTE--this is true in the case of my great-nephew. Both his parents have black hair, his grandfather--my brother--has dark brown hair, but his great-grandfather--my Dad--had red hair).

      In modern-day UK, despite being it one of the places with the highest populations of redheads, the words "ginger" or "ginga" are derogatorily used to describe red-headed people, with terms such as "gingerphobia" (fear of redheads or "gingerism" (prejudice against redheads) used by the media. Redheads are also sometimes referred to disparagingly as "carrot tops" and "carrot heads". "Gingerism" has been compared to racism, although this is widely disputed and bodies such as the UK Commission for Racial Equality do not monitor cases of discrimination and hate crimes against redheads. A UK woman recently won an award from a tribunal after being sexually harassed and receiving abuse because of her red hair , and a family in Newcastle upon Tyne, England, was forced to move twice after being targeted for abuse and hate crime on account of their red hair, and in 2003, a 20 year old was stabbed in the back for "being ginger."

     If you understand the study of genetics, there is a part on what causes red hair in the wikipedia article.

Answer 3

It's a little more complicated than that. If your redheaded grandmother was your father's mother, then you didn't get the genes for her red hair. You got your father & grandfather's Y chromosome.  And remember -- having 4 children doesn't ensure one child with red hair. The probably is 25% for each individual child.
