What type of allele is masked when a dominant allele is present?
recessive trate
What is an allele whose trait always shows up in the organism?
type 2 Diabetes
What type of trait prevents the other type from being seen?
A recessive trait. When a recessive allele is with a dominant allele, only the dominanate trait can be seen.
What type of allele masks the expression of the recessive allele and is therefore expressed in the heterozygous?
A dominant allele will mask the prsence of a recssive allele
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 type of allele is masked when a dominant allele is present?
recessive trate
What type of allele is in the all of the egg nuclei?
the dominant allele is in all egg nuclei.
What is an allele whose trait always shows up in the organism?
type 2 Diabetes
What type of trait prevents the other type from being seen?
A recessive trait. When a recessive allele is with a dominant allele, only the dominanate trait can be seen.
What is a type of degenerative disease cause be a dominant allele?
Huntington's Disease.
How does allele cause a trait in an organism?
the allele causes a certain type of protein to form-apex
Is the following sentence true or false all genes show simple patterns of dominant and recessive alleles?
False. Blood type genes have two dominant alleles (A and B), and one recessive (O). When a person gets one A allele and one B allele, they then have the blood type AB. Both are expressed equally. In other genes, a dominant allele might not be completely dominant, allowing the recessive allele to be partially expressed.
What type of allele masks the expression of the recessive allele and is therefore expressed in the heterozygous?
A dominant allele will mask the prsence of a recssive allele
How do you use recessive allele in a sentence?
The building blocks of our genes (that make us what we are) are called alleles and these can be either dominant, recessive or codominant - which means they are equally dominant. Now for your sentence: "A typical example of codominance can be found in blood types, where the existence of A as well as B alleles in a person will lead to blood type AB".
What type of allele masks the expression of the recessive allele?
Two recessive alleles can not take over a dominant allele because there are only two alleles in a pair. This can only happen if there is a mutation because the dominant always takes over the recessive.
How do you write the genotype for a trait?
Genotypes are written differently depending on what gene you are referring to. A capital letter means that allele is dominant over an allele written with a lower case letter. For example B is dominant over b. Some genotypes are written using a superscript, such as IAIB for the genotype of a person with blood type AB. Or HbsHbs for a person with sickle cell anaemia (compared to HbSHbS for a person without sickle cell). In this case Hb stands for haemoglobin. Usually the letters chosen relate to the trait involved... for example, if talking about tall plants T would be used to represent the tall allele and t would represent the short allele.
In a punnet square a small letter stands for what type of allele?
A small letter stands for a recessive allele.
