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).*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'.
It is a genetic similarity between two organisms.
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.
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".
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.
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.
Heterozygous dominant. Could also be called a masked trait.
The weaker trait is called the recessive trait The stronger one is called the dominant trait
dominant
The recessive allele.
recessive
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.
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.
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.
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).
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.
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.
