What gene is defined as a gene that controls the appearance of a certain trait?
The gene defined as controlling the appearance of a specific trait is referred to as the "gene for that trait" or "trait-specific gene." These genes can influence physical characteristics like eye color, height, or leaf shape.
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".
How do combination of alleles on your genes determine your phenotype?
Your phenotype is a characteristic of how you look, for example if you have brown or blue eyes. You inherit one allele for each characteristic you have from you mom and dad. Say your mom gives you a blue eyes allele and your dad gives you a brown eyes allele. Since brown eyes usually dominate over blue eyes, you would most likely be heterozygous for brown eye color, and you would have brown eyes. This would be represented by Bb, the B standing for brown eye color, the dominant trait, and the b standing for blue eye color, in this case the recessive trait. So, depending on what alleles you receive from your parents, you may look different than, for example, than your siblings do because they got a different set of alleles. This is possible because your parents both have 2 alleles, but they only give you one of each, so if both your parents give, for example, your sister a blue eye allele, she will most likely have blue eyes, even if you have brown.
What is A version of gene is called?
Particular Versions of Genes are called Alleles - one way they differ is that some alleles are termed to be dominant while others are termed to be recessive.
What does it mean to have a dominant eye?
Having a dominant eye means that one eye provides the brain with a slightly stronger signal than the other eye, which can affect depth perception and focus when looking at objects. It is important to know which eye is dominant for activities like shooting, archery, or photography to improve accuracy and performance.
An organism that has an allele for brown eyes and an allele for blue eyes you?
are likely heterozygous for eye color. This means you have two different alleles for eye color - one for brown eyes and one for blue eyes. The dominant allele for brown eyes may result in you having brown eyes, but you still carry the blue eye allele.
Are blue or brown eyes dominent?
Brown eyes are considered dominant over blue eyes. This means that if a person has one parent with brown eyes and one parent with blue eyes, they are more likely to have brown eyes. However, eye color inheritance can be complex and is controlled by multiple genes.
How does alleles help to explain why we look different?
Alleles are different forms of a gene that can produce varying traits or characteristics, such as eye color or hair texture. When we inherit alleles from our parents, the combination we receive influences how we look. For example, if one parent passed on a dominant allele for brown eyes and the other a recessive allele for blue eyes, the dominant brown allele would likely determine our eye color. Thus, alleles play a key role in determining our physical appearance.

The gene defined as controlling the appearance of a specific trait is referred to as the "gene for that trait" or "trait-specific gene." These genes can influence physical characteristics like eye color, height, or leaf shape.
How do you explain the principle of dominance?
Genetic dominance? One gene is dominant over the other gene in the chromosome pair by having it protein product made totally at the expense of the recessive gene, or the protein product dominates production. For instance, blue eye color is recessive to brown eye color. You have two alleles ( different molecular form of the same gene ) in this case; one from one parent and one from the other parent. Only the brown allele expresses and is called dominant then.
Why can a person with brown eyes carry blue eye alleles but a person with blue eyes cannot have a brown eye allele in their genotype?
A person with brown eyes can carry the blue eye allele because brown is a dominant trait, so they can have both blue and brown alleles in their genotype. However, a person with blue eyes cannot have a brown eye allele because blue eyes are a recessive trait, meaning they must have two copies of the blue allele in their genotype to express the trait.
What is dominant and recessive allele?
A dominant allele is an allele where its phenotype will always be represented when the allele for that gene is present. A recessive allele can be masked by a dominant allele when a dominant and recessive allele are present for the same gene. A recessive allele will only present itself when two recessive alleles for a trait are present.
What would a person who is heterozygous for eye color have?
A person who is heterozygous for eye color has two different alleles for eye color. This means they have inherited one allele for brown eyes and one allele for blue eyes, for example. The dominant allele usually determines the physical trait that is expressed, so in this case, the person's eyes would likely be brown.
What eye colors are dominant and which are recessive?
Brown eye color is dominant, while blue, green, and hazel eye colors are recessive. This means that brown eyes are more likely to be expressed if an individual inherits one brown-eyed allele and one allele for a different eye color.
What is simple dominance?
Simple dominance is a concept in genetics where one allele (gene variant) masks the expression of another allele at the same locus. This results in the dominant allele being expressed phenotypically, while the recessive allele is not expressed. This type of inheritance pattern is common in traits like eye color or hair texture.
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.
