There is no simple dominant or recessive pattern for hair whorl direction. It is influenced by multiple genetic factors and can be different among individuals in the same family.
curly hair, as the dominant gene overrules the recessive gene I THINK :)
Yes, it is called co-dominance. It appears in hair textures and, well, other stuff. example: straight hair is hh wavy hair is Hh curly hair is HH there is no dominant, just a sort of blend, even though wavy hair is more likely.
If one parent has black hair (dominant) and the other parent has white hair (recessive), the offspring will likely have black hair, as the dominant gene for black hair will override the recessive gene for white hair.
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.
In simple Mendelian genetics, there may be several alleles (variations) for a given trait. since organisms generally have two pairs of chromosomes, they have two alleles. A dominant allele is one that when it is present, always shows itself. A recessive allele only shows when there are two copies of the recessive allele. For example, suppose brown hair is dominant and black hair is recessive. If there are any copies of the brown hair allele, the person's hair will be brown. A person's hair will be black only if they have two copies of the black hair allele. In reality, genetics is much more complicated than simply dominant and recessive as many genes may influence one trait.
No, it is recessive.
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
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.

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.)
Straight hair is typically controlled by a dominant allele. Curly hair is usually controlled by a recessive allele.
If one parent has black hair (dominant) and the other parent has white hair (recessive), the offspring will likely have black hair, as the dominant gene for black hair will override the recessive gene for white hair.
There are no such things as dominant and recessive genes. There are only dominant and recessive alleles. Dominant alleles are parts of a gene that present its features over the recessive allele, which is the one that is always masked by the dominant allele. The recessive allele's trait only shows if both of the alleles in a trait are recessive.
A Whorl is a section of hair that grows in a circular pattern. A nape whorl is a whorl of hair that grows at the nape of the neck, whorls can also grow on one's crown.
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.
Well, black hair is the most dominant, but if you were comparing, say, blond hair to brown hair then the brown hair would be dominant. I am studying this for collage right now so I an pretty sure this is right, if it's not i am so doomed :0!!! lol! hope that helped, Aquilo
