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.

∙ 14y agoit depends if the person that has white skin is a man or a woman. if the man has white skin then it is dominant. if the woman has white skin it is recessive

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.
In sheep the allele for white wall parentheses A is dominant over the allele for black wall parentheses a how do you determine the genotype of a white ram or male sheep?
To determine the genotype of a white ram, breed him with black females. Black females are homozygous recesive for the black trait, a. If the ram is homozygous dominant, all offspring will be white (and heterozygous). If the ram is heterozygous, approximately half of it's offspring will be white and half will be black.
What happens when an allele is dominate or recessive?
Well, a dominant allele carries dominant traits from parents to offspring. An example of a dominant trait is brown hair and brown eyes because these traits are most likely to show up on a human than a recessive allele. A recessive allele may carry a recessive trait from parents to offspring such as blonde hair and blue eyes, these are uncommon because they are recessive traits.
What is the difference between dominant and recessive alleles for specific traits?
Dominant is an allele that will always be expressed in a heterozygous individual. Recessive on other hand are traits that will only be expressed in a homozygous condition. Organisms receive one allele for each trait from each parent, thus you have two alleles for each trait.
What is a dominent allele?
A dominant allele is an allele that can take over a recessive allele, so if you have a dominant allele and a recessive allele, then the offspring will most likely have a dominant allele over a recessive allele. The dominant allele is expressed over the recessive allele.
Allele that is always expressed if present?
An allele that is always expressed when it is present is the dominant allele.
An allele that is dominated or cover up by another allele is called what?
It should be a dominant allele--a dominant allele's trait will be expressed over the recessive allele's trait.
How does an allele trait in an organism?
An allele causes a trait by either being dominant orrecessive or example, allele A will occur over allele a because it is dominant.
In the pea plants the presence of an allele for purple flowers will mask presence of an allele for white flowers. What does that mean?
Gene responsible for purple color is dominant over white color.
In fruit flies gray body color is dominant over black body color?
The statement, "In fruit flies, gray body color is dominant over black body color" is true. The allele for gray body color is dominant.
Is when one allele completely masks another?
when one allele is completely dominant over another allele, then it masks the expression of the second allele so the allele that masks the effect is called dominant allele and the allele whos effect is masked is called recessive allele
Why do we call some alleles dominant?
because it dominates the phenotype
