Since multiple alleles are at play, there’s a full spectrum of hair color possibilities. Most of what you’ll read about genetics presents hair color as either dominant or recessive. One theory used to be that red hair was a recessive condition: ie that both your parents carried a gene for red hair while also having one for dark hair. It turns out, there are many different shades of brown. Also, not only in puberty, it is common for children to change hair color growing up. Depending on the genotypes of the black- and red-haired parents, you could get anything, blonde, mousy, red, dark brown, reddish brown, reddish black or black. The science makes sense, but according to the Tech Museum of Innovation, most of what we know about hair color is still in the theory stage. The gene responsible for producing eumelanin (causes black hair) probably turn on, or the gene responsible for pheomelanin (causes red hair) probably turn off. Answer (1 of 15): It could go a multitude of different ways. People used to think that if one parent had blonde hair and the other had brown hair, for example, the recessive (blonde) would lose out and the dominant (brown) would win. If you produce a lot of the melanin type eumelanin, you probably have black or brown.
When the genes meet, the resulting expression is your baby’s unique phenotype, or physical trait. It is entirely possible for Black people to be born with red hair without being biracial, too. Hair color comes from melanin, a pigment in your skin, hair, and eyes.
Dominant alleles are associated with dark hair, while recessive alleles are linked to fair shades. You might remember the terms “dominant” and “recessive” from grade school science class. You may be faced with an approaching deadline. The dream is a premonition for sorrow, disillusionment, or betrayal. You are refusing to conform to some idea or attitude. There is something that you need to get out of your head. How exactly do genes interact to create hair color? Each of your baby’s genes are made up of alleles. Dream about baby with black hair draws attention to conscious reality, deliberate action and rational thoughts.
