What is an individual who has a recessive disease causing allele at a particular gene on one chromosome and a normal allele at that gene on the other chromosome?
An individual with a recessive disease-causing allele on one chromosome and a normal allele on the other chromosome is referred to as a heterozygote for that gene. Since the disease is recessive, the normal allele typically masks the effects of the recessive allele, meaning the individual usually does not exhibit symptoms of the disease. However, they can still pass the recessive allele to their offspring.
When one allele shows dominance over another allele?
In cases of complete dominance, one allele, known as the dominant allele, masks the expression of the other allele, known as the recessive allele, in the heterozygous state. This results in only the dominant allele being expressed in the phenotype.
Is this true or false The allele AA is homozygous dominant?
True. The allele AA represents a homozygous dominant genotype, meaning that both alleles at a particular gene locus are the same and both are dominant. In this case, the individual has two copies of the dominant allele A.
What is the meaning the word dominant?
adj; having power over or overlooking others
An allele that is dominated or cover up by another allele is called what?
An allele that is dominated or covered up by another allele is called a recessive allele. This means that the trait associated with the recessive allele is only expressed when an individual carries two copies of that allele.
What is caused by a dominant allele located on an autosome?
A dominant allele located on an autosome will be expressed phenotypically in the individual, meaning it will be visible in the physical characteristics of the organism. This dominant allele will mask the effects of any recessive allele at the same locus.
What word describes physical appearance?
allele
What makes dominant alleles different from recessive alleles?
It's in the word! Dominant means bigger or stronger or greater. So the dominant allele is the stronger gene that is going to show whereas the recessive allele is still in you, but is overshadowed by the dominant allele.
How do you pronounce the word allele?
It is pronounced a lee el
Can you give a sentence using the word allele?
I like alleles.
What is an allele and what is a nasty allele?
Allele is word used by Mendel for counter parts of an elementon later called factor and renamed as gene e.g. T and t are alleles for a gene that controls height in pea plant .Nasty allele is not biological term .Note word elementon is technical term used by Mendel , it is not element used in Chemistry .
What is an individual who has a recessive disease causing allele at a particular gene on one chromosome and a normal allele at that gene on the other chromosome?
An individual with a recessive disease-causing allele on one chromosome and a normal allele on the other chromosome is referred to as a heterozygote for that gene. Since the disease is recessive, the normal allele typically masks the effects of the recessive allele, meaning the individual usually does not exhibit symptoms of the disease. However, they can still pass the recessive allele to their offspring.
What the meaning of genoytpe?
It is the set of genes that an individual has, or it can refer to what allele of a particular gene an individual has.
When one allele shows dominance over another allele?
In cases of complete dominance, one allele, known as the dominant allele, masks the expression of the other allele, known as the recessive allele, in the heterozygous state. This results in only the dominant allele being expressed in the phenotype.
What is true of the allele pair of someone with a genotype TT?
The allele pair of someone with a genotype TT is homozygous dominant.
Why is it that a person with an allele for a particular trait may not have a phenotype that shows the trait?
a dominant allele will express its trait , as well as be carried by the person. the word carrier is commonly used for a person who bears an allele which does not express itself(i.e. a recessive gene).
What is allele masked by the dominant allele?
An allele that is masked by the dominant allele is called a recessive allele. When an individual has one dominant allele and one recessive allele, only the trait determined by the dominant allele will be expressed. The recessive allele will only be expressed if an individual has two copies of it (homozygous recessive).
