No it's a phenotype because it says the physical characteristic if it was like Bb for example it would be the genotype. (I just made Bb up, that's not actually the genotype for brown hair color!)
False. A combination af alleles is called a gene. The genotype is the type of gene (I.e blue eyes rather than brown eyes)
The genotype is the combination of genes, for example, one inherited brown hair gene is a B (dominant), and one blond hair gene is a b (recessive). The possible genotypes in this example are BB, Bb, and bb. A phenotype is the real-world description of the trait, so the phenotypes for the genotypes listed above would be, in order, brown, brown, and blond. obviously, this is a simplified example. Possible phenotypes for hair color vary widely, and are ever natural color of hair possible: black, brown, light brown, blonde, red, strawberry blonde, etc.
Yes, and no. It's the expression of a genotype for hair color.
An organism's genotype is its genetic identity. The genotype is comprised of all the genetic material inherited from both parents. The genotype is what "tells" each individual cell how to function. The phenotype is the physical expression of an organism's genotype. For example, if a person's genotype for eye color is one dominant allele for brown and one recessive for blue, then the individual's phenotype would be their actual eye color which in this case would be brown.
A phenotype is the actual result that you can actually see, whereas the genotype is the allele or gene that causes the phenotype. Lets say that brown hair is dominant and which is caused by an allele that we'll represent with B, and lets say that red hair is cause by a recessive allele that we'll represent with b. A genotype is represented by a combination of 2 of these alleles. So we have BB, Bb and bb as our possible genotypes of the child. One of the alleles is from the mom and the other from the dad. BB means that both of the parents have brown hair, which means the offspring will have brown hair, and since both parents have brown hair and brown is dominant, we call the offspring homozygous dominant for that genotype. Homozygous means the same. Bb means that on parent has brown hair and the other has red hair or at least carries the red hair trait. This offspring will have brown hair because B is dominant over b. We call this heterozygous dominant. Heterozygous means different. Last we have the bb. this means that either both parents have red hair or both have the traits for red hair. This offspring will have red hair because they do not have any dominant genes. This is called homozygous recessive. Now this is just an example. hair color is gets much more complicated then this but that's the basic idea for all genotypes and phenotypes. I hope this helps at least some.
25% of the offspring will have the recessive genotype for hair colour.

Her hair color is brown.

The genetics of hair colors are not yet completly established. At least two gene pairs control human hair color. Your mom probably has blonde (bb) and red (rr) genes. Giving her a bbrr genotype (what is in the genes). Your dad must carry red also since you have red hair . Red is recessive to the brown. His genotype is BbRr. There is more to it than this as this doesn't account for the shades of hair color we see. But yes, this is possible.
The color of his hair is brown. You can see his natural color in his eyebrows.
brown
Beyonce's real hair color is brown.
Yes, and no. It's the expression of a genotype for hair color.
A genotype can tell what genes you have in your chromosomes. Genotypes really means what are all your genes and phenotype is what you see. You may have brown eyes. Your genotype might show that you have brown and blue genes for eye color but you see only brown.
light brown hair
Helen Keller's hair color was dark brown.
