Yes and No.
There is no such thing as black skin gene and white skin gene. There are many genes that decide the pigmentation of skin.
Since 1910 researches have known that human skin pigmentation is "Polygenic"(Pertaining to two or more genes. As opposed to monogenic").
It is not as simple as black vs white equals black. Infact that is impossible.
Since a very dark skinned black person who has offspring with a very light skinned white person will never produce a very dark skinned black offspring. And them genes will be lost forever. However the same is not true the other way around.
We have known that complexion is polygenic, rather than the result of one gene with many alleles, because breeding of palest with darkest yields a spectrum of offspring genotypes from the same parents
We have known that human pigmentation genes are additive and codominant because half the offspring of differently skin-toned parents have a complexion between that of their parents (no matter how similar the parents).
Several independent genes must work in concert to produce the deepest complexion-the extreme of the darkness adaptation.
Where knowledge has improved over the past century has been in precisely how many genes are involved and their specific loci.
As of 1998, five human pigmentation genes had been identified. Their symbols and genome loci are: "TYR" at 11q14-21, "TYRP1" at 9p23, "TYRP2" at 13q31-32, "P" at 15q11.2-12, and "MC1R" at 16q24.3 (Sturm, Box, and Ramsay 1998).
Many things can go wrong and, when they do, the result is a lighter complexion. For instance, deleterious mutations at the five loci above result in various forms of albinism,
But no genetic defect can make the child of light-skinned parents come out dark.
Another words. You need two dark parents to produce a dark child. But you don't need two white parents to produce a white child.
Also. Black vs white = most likely equals brown. So neither skin tone wins.

What does The presence of an allele for purple flowers will mask the presence of an allele for white flowers mean?
Gene responsible for purple color is dominant over white color.
Genes that are only seen when paired with a recessive gene?
if u have a recessive gene with a recessive gene then u can see the recessive gene but if you have a dominant gene with a recessive gene you can only see the dominant gene hope that helps:)
What genes are recessive traits?
These traits are called dominant traits. They will overcome the recessive gene and the dominant trait will be expressed. A recessive gene needs two alleles present in its genotype to be expressed.
What is the different between dominant and recessive?
Dominant trait is the one which is expressed when the homologous pair of genes controlling it are either homozygous or Hetrozygous dominant; on the other hand recessive trait has both genes to be homozygous recessive. in fact trait is controlled by the form of genes. Dominant gene expresses even when it is in the company of recessive gene. However recessive gene expresses only when in company of recessive gene
Describe the offspring of a true breeding white flowering plant?
More true breeding white flowered plants. If the gene combination for white is WW and is dominant a cross of WW x WW would result in 100% WW (white flowered plants)
What does The presence of an allele for purple flowers will mask the presence of an allele for white flowers mean?
Gene responsible for purple color is dominant over white color.
During slavery did white men sleep with black women?
The Black gene is more powerful than the white gene, ALSO WHITE WOMEN raped the blackmale slaves more so that the white man raping the black women ,which is spoken of less.
What skin color is dominant white or black?
Skin colour does not follow the rules of being dominant or recessive. Skin colour is controlled by more than one gene or the amount of pigment melanin. So if one parent is white and the other is black, they will end up having a mixed coloured child because the colours blend together.
What is an example of a non polygenetic trait?
Coat color and pattern is a polygenic trait, meaning it is controlled by more than one gene or gene complex. A dog with the gene for black color expression may also have the gene for suppression of black and so have a red or yellow coat. Or a dog with the brindle gene may have one or more of the genes for large areas of white and so have little or no brindle coloring visible. A dog with the dominant black gene may have genes for color fading and appear gray or merle.Rate This Answer
What type of gene causes traits that are more likely to occur?
a dominant gene.
Genes that are only seen when paired with a recessive gene?
if u have a recessive gene with a recessive gene then u can see the recessive gene but if you have a dominant gene with a recessive gene you can only see the dominant gene hope that helps:)
How does dominance apply to heredity?
If some gene is dominant it will always be more hereditary than a non-dominant gene. Like brown eyes, the brown eye gene is dominant so a couple with blue and brown eyes will have a child with brown eyes no matter what.
Are you more likely to have blond hair or brown hair?
You are more likely to have brown hair because the brown hair gene is a dominant gene, and not the blond hair gene.
What genes are recessive traits?
These traits are called dominant traits. They will overcome the recessive gene and the dominant trait will be expressed. A recessive gene needs two alleles present in its genotype to be expressed.
Is the black skin allele dominant over the white skin allele?
there is neither a "black skin" allele nor a "white skin" allele. skin color is accountable to myriads of factors & not attributable to a single gene. perhaps this question comes out from an attempt to guess the shade of a mixed-race child. simply put, there is no telling what color a child will come out. sometimes more of the father's complexion will show; othertimes vicer-versa.
When a particular inherited characteristic is controlled more by one gene of a pair than by the other the stronger gene is called?
dominant
What is the different between dominant and recessive?
Dominant trait is the one which is expressed when the homologous pair of genes controlling it are either homozygous or Hetrozygous dominant; on the other hand recessive trait has both genes to be homozygous recessive. in fact trait is controlled by the form of genes. Dominant gene expresses even when it is in the company of recessive gene. However recessive gene expresses only when in company of recessive gene
