How do a blonde and a brunette have a redheaded child??

Question

Is it a skipped gene or something else??

Answer 1

Ugh, awful answers.

There are at least 2 genes known to affect hair color, and in all liklihood, there is at least a 3rd if not more. Aside from the commonly known blonde/brown gene, there is a second gene that deals with phaeomelanin production, this gene is known as red/not-red. Red hues are higher in phaeomelanin concentration than non-red hues. It is likely that the red allele came from the brunette parent, but was just not so noticable with their darker hair coloring.

Answer 2

Lots of blond people have recessive redheaded genes.

Answer 3

I am blonde, my childs father is a burnette and we have a red headed 5 year old girl. We traced it to my grandfather, he was kind enough to donate the gene!!

Answer 4

Somewhere on both sides of the family there are recessive red hair genes.

Answer 5

Both parents are carrying a recessive gene for red hair. The chances are low, but it does happen.

Answer 6

Some where in the family of her or his must have been some reheaded people. My mother and father both had brown hair and had a redhead son. My father had a brother with red hair.

Answer 7

its genetics; even if the actual parents don't have red hair, if the parents' distant reletives had the red hair, then the gene can be passed down from generation to generation--ask a biology teacher.

Answer 8

because someone in one of there family has red hair so the child inherited that gene.

Answer 9

Usually there would be a skipped gene on both sides, but maybe there was an irsih postman....

Answer 10

If the one of the biological parent has an affair with a red head.
Gene mutation is probable but not likely.
