What is an organism with one dominant and one recessive gene for a trait?
An organism with one dominant and one recessive gene for a trait is called a heterozygote. In this case, the dominant gene will be expressed in the organism's phenotype, while the recessive gene will not be expressed unless the organism inherits two copies of the recessive gene.
What type of trait is only seen if its gene is present in both gametes that unite to start the life of a new organism?
Recessive trait. This type of trait is only expressed when the individual has two copies of the gene for that trait, one from each parent. If only one copy is present, the dominant trait will be expressed.
What are the pair of alleles for a trait and how do they determine the expression of that trait?
Alleles are pairs of genes that determine a specific trait in an organism. Each parent contributes one allele, and the combination of alleles determines how the trait is expressed. If the alleles are the same (homozygous), the trait will be expressed in a certain way. If the alleles are different (heterozygous), one allele may be dominant and determine the trait's expression, while the other may be recessive and not expressed.
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.
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.
The trait is one expressed in a hybrid organism?
In a hybrid organism, a trait is one that is a result of combining genetic information from two different parent organisms. This trait may be a combination of traits from both parents or a new trait that arises from genetic recombination during hybridization.
What is meant by dominance and recessiveness?
First of all alleles code for different traits all across an organism. Simply looking at it, a dominant allele is a trait that essentially "dominates" or is expressed over a recessive allele. In theory every organism (that is not asexual) receives one allele from its father and one allele from its mother. If both of these alleles are dominant (homozygous dominant) than the dominant trait is expressed, if one is dominant and one is recessive (heterozygous) than still the dominant trait is expressed. However, if the alleles for both traits are recessive (homozygous recessive) than the recessive trait will be expressed.
Why does an organism have one factor for a dominant trait and one factor for a recessive trait?
Organisms have two factors (alleles) for a trait because they inherit one from each parent. Dominant traits are expressed when at least one dominant allele is present, while recessive traits are only expressed when both alleles are recessive. This is known as Mendelian inheritance.
A plant that is hybrid for a trait is?
Has one dominant and one recessive gene for that particular trait.
What is an organism with 2 alleles for 1 trait that are different?
The answer to your question, "What is an organism with 2 of the same alleles for a trait called?" is homozygous. it is just homozygous-By SciienceFreak
What is a trait that is expressed even if only one gene for that form of the trait is inherited?
It is a dominant trait. You only need one gene of a dominant trait for that trait to be expressed. You need two copies of the recessive trait in order for the trait to be expressed.
What is an observable trait of an organism that can mask a recessive trait?
The observable characteristic are called the genotype and any dominant trait can mask the recessive. An example would be Black Angus cattle can actually carry a red recessive trait because black is the dominant trait in cattle breeding
