DNA
actually it is not DNA at all, a dominant trait, masks a recessive trait. <3hope this helped. 8)*well that is wrong also, it is the dominant factor. The dominant factor because it masked, or dominated, the factor for the other trait in the pairs. (Holt Biology text book).*
What else can I help you with?
Condition of being heterozygous for a recessive trait?
If you are heterozygous this means you carry both a dominant and recessive allele. if you are heterozygous for a recessive trait then you will have a dominant and recessive allele. example: let T represent tall and t represent short. a person with heterozygous for a recessive trait will have 'Tt'.
An individual who is homozygous is what?
It is a genetic similarity between two organisms.
What does it mean if there is two different alleles for a trait?
The trait could show up in two different forms. Alleles are individual units that determine what trait will be expressed in an offspring. Alleles exist for most traits such as hair color or wing size. Having two alleles simply means that the trait can be expressed in different variation. One trait can have several different alleles.
What is the definition of homogeneous?
Both alleles of one trait are either dominant or recessive. Not one dominant and one recessive. For example, the homogeneous hair of a cat would have both alleles of that trait be the same, say, BB or bb. NOT Bb.The above definition applies in the field of genetics. More generally, the word means "Of the same or similar nature or kind".
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.
Trait of an organism that can be masked by the dominant by the dominant form of a trait?
A recessive trait is a characteristic of an organism that can be masked by the dominant form of a trait. It is only expressed when an individual inherits two copies of the recessive allele. Examples include blue eye color being masked by brown eye color.
What is it called when a trait that is not seen when a dominant gene is paired with a recessive gene?
Heterozygous dominant. Could also be called a masked trait.
13 What is the name of a weak trait that is masked by a stronger trait?
The weaker trait is called the recessive trait The stronger one is called the dominant trait
What type of trait that is masked or covered?
dominant
When on e allele of a gene masks the presence of the other allele what form is masked?
The recessive allele.
In a hybrid individual the trait that is covered and not expressed is the what trait?
recessive
When a trait is not expressed when paired with a dominant allele is the definiton of?
The trait that is not expressed when paired with a dominant allele is known as a recessive trait. It is masked by the dominant trait in individuals carrying both alleles.
Trait of an organism that can be masked by the dominant form of a trait?
A recessive trait is one that is not expressed when paired with a dominant trait. It may only be visually evident when both copies of the gene carry the recessive form.
Is it true that mendel assumed that a dominant allele had masked the corresponding recessive allele in the f1 generation?
Yes, Gregor Mendel's principle of dominance stated that in the F1 generation, the dominant allele would mask the expression of the corresponding recessive allele. This means that only the dominant trait would be observed in the offspring.
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).
What is trait called that appear only when both alleles are present?
A trait that appears only when both alleles are present is called a recessive trait. In this case, the trait is masked when the dominant allele is present, but becomes visible when two copies of the recessive allele are inherited.
When traits seem to disappear when two different genes for the same trait are present?
NO, the traits do not disappear they are simply "masked". According to Mendelian theory there are DOMINANT (A) and RECESSIVE (a) traits. When Aa is present the recessive trait is masked therefore it does not show up. These are called alleles.
