Technically, black hair is neither dominant or recessive. There are many types of hair colors, so hair color (like eye or skin color) is polygenic. This means there many different genotypes for an array of phenotypes. In a test I recently took, there was a problem with what you are talking about. It stated: the more dominant alleles you have in a set of 8 or 9 pairs of alleles, the darker the hair color. So if both parents originally have black hair, the child would get the most amount of dominant alleles to get black hair too.
Ex: AABBCCDD and AABBCCDD would give the child AABBCCDD too. This would result in black hair.
(This is very basic. There might be a lot more, but I am not positive)
What else can I help you with?
The gene for red hair is recessive to the gene for black hair. What will be the hair colour of a child if he inherits a gene for red colour from his mother and a gene for black hair from his father Ex?
The child will have black hair because the gene for black hair is dominant over the gene for red hair. Since the child inherits one gene for red hair from the mother (recessive) and one gene for black hair from the father (dominant), the dominant black hair gene will express itself. Therefore, the child's hair color will be black.
Cattle with both white hair and red hair are?
Mendel's principle of dominant and recessive alleles doe not explain why the heterozygous chickens have both red and white hair
How do dominant alleles recessive alleles differs?
Dominant alleles are the ones that show up in the phenotype. Recessive alleles do not unless both alleles are recessive, but can be passed on. For example: Tt , T=tall and t=short. Tall is dominant and short is recessive. You are tall and can pass on the short gene. Or, you can use black hair being dominant over red. Or, brown eyes being dominant over blue. Dominant can be seen on you and recessive can't.
Is a red golden retriver dominant or recessive?
In golden retrievers, red is recessive to yellow.
If a baby goat received dominant gene for curly hair from one parent and recessive gene for straight hair from the other which trait will the baby goat display?
curly hair, as the dominant gene overrules the recessive gene I THINK :)
What does a recessive trait for blonde hair and a recessive trait for red hair make?
This may cause a lighter red or a darker blonde. actually that isn't true. it depends on which one is the dominant trait. which one is homozygous which one is heterozygous. it all depends.

Therefore, the child's hair color will be black.
Compare and contrast dominant and recessive?
In genetics, each organism will typically have 2 alleles for each trait. For a trait such as hair color, you might have an allele for red hair from your dad and an allele for brown hair from your mom. The trait for brown hair happens to be dominant to the trait for red hair so you would show the allele for brown hair. (In other words, you would have brown hair.)
Is the straight hair dominant?
No, it is recessive.
Can someone give you a List of dominant or recessive personality traits?
1. Shape of face (probably polygenic) Oval dominant, square recessive 2. Cleft in chin No cleft dominant, cleft recessive 3. Hair curl (probably polygenic) Assume incomplete dominance Curly: homozygous Wavy: heterozygous Straight: homozygous 4. Hairline Widow peak dominant, straight hairline recessive 5. Eyebrow size Broad dominant, slender recessive 6. Eyebrow shape Separated dominant, joined recessive 7. Eyelash length Long dominant, short recessive 8. Dimples Dimples dominant, no dimples recessive 9. Earlobes Free lobe dominant, attached recessive 10. Eye shape Almond dominant, round recessive 11. Freckles Freckles dominant, no freckles recessive 12. Tongue rolling Roller dominant, nonroller recessive 13. Tongue folding Inability dominant, ability recessive 14. Finger mid-digital hair Hair dominant, no hair recessive 15. Hitch-hiker's thumb Straight thumb dominant, hitch-hiker thumb recessive 16. Bent little finger Bent dominant, straight recessive 17. Interlaced fingers Left thumb over right dominant, right over left recessive 18. Hair on back of hand Hair dominant, no hair recessive 19. Tendons of Palmar Muscle Two tendons dominant, three tendons recessive
Is red hair a ressesive gene?
Yes, red hair is typically considered a recessive genetic trait. In order for a person to have red hair, they must inherit two copies of the recessive gene associated with red hair color from both parents.

What determines whether a person will have dominant or recessive hair color?
Hair color is determined by genes inherited from parents. Dominant genes for hair color will be expressed over recessive genes, resulting in the dominant color being displayed. If both parents pass on recessive genes, the recessive color will be seen.
Is a red golden retriver dominant or recessive?
In golden retrievers, red is recessive to yellow.
If you have a child with reddish brown hair but the parents are brown and black headed with blue and brown eyes how can the child have red in his hair?
......... Perhaps the grandparents have red hair. LOok up- dominant and recessive traits.

curly hair, as the dominant gene overrules the recessive gene I THINK :)
