Does a recessive allele need another recessive allele to be expressed?
I think if an allele "want" to be expressed, then it has to have a dominant allele. They don't need another recessive allele.
What is a Reciessive form of an allele?
A recessive form of an allele is one that is only expressed in the presence of another recessive allele.
When the expression of one allele is masked by the presence of another is said to be?
Recessive
What are two diseases linked to the X chromosome?
One disorder could be colorblindness. Colorblindness is most common in males because in order to have to disorder you must carry two mutated X chromosomes. Another recessive genetic disorder you can get is called Hemophilia. This is a disorder in which the genes for hemoglobin are not present and your body is not able to create blood clots and a simple scratch can be very serious.
A gene is recessive when?
Most genes have two copies of each gene with dominant gene "trumping" the recessive one. The gene is recessive because it is said not to do much of anything unless paired with another recessive gene, but if paired with a dominant gene, the dominant gene wins.
Is type o blood a type of recessive genetic disorder?
Nope... Its just another type of blood.. its the recessive one...."Universal Donner "!
Under what condition can a female acquire an X recessive disorder?
Both X chromosomes must carry the recessive trait. Since males only have one X chromosome, it is much easier for males to have the recessive phenotype. Put another way, a female would have to receive an X chromosome with the recessive gene from both parents, which would mean the father already displays the recessive disorder.
How is a carrier different from a person who has genetic disorder?
A carrier means that you have the gene for the disorder, but because the gene is recessive (meaning that it only shows when you have two recessive genes) and you obviously have a dominant gene as well, you won't show the disorder. Someone who actually has the disorder has two recessive genes. D = dominant gene r = recessive gene Dr = carrier, no signs rD = carrier, no signs DD = not a carrier, no signs rr = has the disorder
Does a recessive allele need another recessive allele to be expressed?

What does recessive allele mean?
Recessive allele disorders are just as they sound - they are disorders that are a result of a prevalent recessive allele in one's genetic makeup. A recessive allele disorder will rarely occur since it is dependent on the crossing of two heterozygous parent cells, but it can lead to interesting consequences. An example of a recessive allele disorder is hemophilia - the body's inability to clot blood - and it has affected much of the European royalty in history, such as Queen Victoria of Great Britain.
What are two sex-chromosome disorders?
One disorder could be colorblindness. Colorblindness is most common in males because in order to have to disorder you must carry two mutated X chromosomes. Another recessive genetic disorder you can get is called Hemophilia. This is a disorder in which the genes for hemoglobin are not present and your body is not able to create blood clots and a simple scratch can be very serious.
How do i put absence in a sentence?

What is another sentence for the word absence?
I felt an absence in my heart when my dog died.
What is a Reciessive form of an allele?
A recessive form of an allele is one that is only expressed in the presence of another recessive allele.
One trait masking another form of a trait?
The trait that is masked is recessive. The trait that does the masking is dominant.
Is another word for a body cell autosomal?
