What is a trait that is not expressed when an organism receives genes for 2 different forms of a trait?
A trait that is not expressed when another is present is referred to as a recessive trait.
When offspring show a blend of the parents traits one allele is dominant over the other?
The results in the offspring hinge on the genetic make up of the parents. Each expressed trait is either the result of a dominant or recessive phenotype. The relative dominance or recessiveness of the alleles doesn't change only the rate at which they are expressed based on the allele present for each obseerved trait in the parents.
If a study of several pedigrees demonstrated that two parents are normal but their daughters and sons express a trait then the trait is controlled by what?
If the trait is exhibited in the offspring of two normal parents, it suggests that the trait is a dominant one. This means that only one copy of the gene is needed for the trait to be expressed. Alternatively, the trait could be influenced by a de novo mutation that occurred in the germ cells of one of the parents.
Why was only one of the parents characteristics for a trait expressed while the other seemed to be lost?
The one that seemed to be lost was actually a recessive trait, which could turn up again in the next generation.
What in term of applied to the trait that is expressed irregardless of the second allele?
The term applied to the trait that is expressed in regardless of the second allele is dominant. In contrast, the term recessive refers to a trait that is expressed when the second allele is identical.
If both parents are carriers what will the child be?
When a recessive trait is inherited from both parents, it will be expressed. If the trait is hemophilia, the child will be a hemophiliac.
The trait observed in the first generation when parents that have different traits are bred?
The trait observed in the first generation when parents with different traits are bred is known as the dominant trait. This trait is expressed in the offspring because it masks the expression of the recessive trait.
What must a true if a boy is born with attached earlobes?
If a boy is born with attached earlobes, it indicates that he has inherited a specific genetic trait. Attached earlobes are typically considered a recessive trait, meaning that both parents must carry the gene for it to be expressed in their child. Therefore, at least one or both of the boy's parents likely have attached earlobes or carry the allele for the trait.
Is closed front teeth a dominant trait?
Closed front teeth is considered a recessive trait, meaning that both parents must pass on the gene for closed front teeth in order for it to be expressed in the offspring. If both parents have closed front teeth, then it is likely that their child will also have closed front teeth.
What is a dominate trait?
Dominant trait is a genetics term. A dominant trait is one which will be expressed if one of the parents has the gene for that trait. A recessive trait is one that will be expressed only if both parents carry the trait.
If both of your parents have a trait are you guaranteed to also inherit that trait?
No it is most likely but it is not guaranteed. Both of my parents don't have widows peaks yet i have a widows peak.
Can a child be afflicted with a dominant trait if both her parents have a normal phenotype Why or why not?
No, a child cannot be afflicted with a dominant trait if both parents have a normal phenotype. This is because dominant traits require at least one copy of the dominant allele to be expressed, and if both parents have a normal phenotype, they would not carry the dominant allele to pass onto their child.
What is a sentence for dominant trait?
A dominate trait is a trait that appears even if an organism has only one factor for the trait.
In a hybrid individual the trait that is covered and not expressed is the what trait?
recessive
What is a trait that is not expressed when an organism receives genes for 2 different forms of a trait?
A trait that is not expressed when another is present is referred to as a recessive trait.
Is right-handedness a dominant or recessive trait?
Right-handedness is considered to be a dominant trait, meaning that it is more likely to be expressed in individuals compared to left-handedness.
What trait is is expressed when two diffrent genes for the same trait are present?
A dominant trait is expressed when two different genes for the same trait are present.
