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.
What else can I help you with?
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 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 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.
Allele that is always expressed if present?
An allele that is always expressed when it is present is the dominant allele.
In mice black hair B is dominant over white b the mouse with the genes BB would have what color hair?
The mouse with the genotype BB would have black hair because the dominant allele B controls for black hair color.
In a certain population of rabbits the allele for brown fur is dominant over the allele for white fur. If 10 out of 100 rabbits have white fur what is the allele frequency for the dominant allele?
In the population of 100 rabbits, 10 have white fur, indicating that they are homozygous recessive (aa). This means that the frequency of the recessive allele (a) can be calculated using the formula ( q^2 = \frac{10}{100} = 0.1 ), so ( q = \sqrt{0.1} \approx 0.316 ). The frequency of the dominant allele (A) is then ( p = 1 - q \approx 1 - 0.316 = 0.684 ). Thus, the allele frequency for the dominant allele is approximately 0.684.
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.
In one allele is dominant to a recessive allele?
In a dominant-recessive allele relationship, the dominant allele will be expressed phenotypically over the recessive allele. This means that even if an organism carries one dominant and one recessive allele for a particular trait, the dominant allele will determine the observable characteristic.
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.
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.
What type of allele is masked when a dominant allele is present?
The recessive allele is masked when a dominant allele is present. Dominant alleles are expressed over recessive alleles in heterozygous individuals.
