How can you tell if a baby will have red hair?
In order to be a redhead, a baby needs two copies of the red hair gene (a mutation of the MC1R gene) because it is recessive. This means if neither parent is ginger, they both need to carry the gene and pass it on — and even then they will have just a 25% chance of the child turning out to be a redhead.
Does red hair show at birth?
People with red hair generally display the phenotype at birth (it is more likely for a redhead to go from having red hair at birth to a darker hair color as they age because you naturally produce more eumelanin as you mature).
Which parent carries the red hair gene?
The gene for red hair is recessive, so a person needs two copies of that gene for it to show up or be expressed. That means even if both parents carry the gene, just one in four of their children are likely to turn out to be a redhead.
Can two redheads have a redhead baby?
For a recessive trait to be expressed the individual must be pure breeding, hence two red heads can not produce any other colour in a child. If red hair is dominant, the chances are one in four that a child will NOT be a red head if mum and dad are both ginger nuts.
Will my baby stay strawberry blonde?
