What else can I help you with?
A hybrid flower would have the genotype?
A hybrid flower could have a genotype that includes a combination of dominant and recessive alleles for certain traits. For example, a hybrid plant may have a genotype like RrYy, indicating it carries one dominant allele for one trait and one recessive allele for another.
Why wouldn't you see a recessive trait?
You wouldn't see a recessive trait if an individual has one dominant and one recessive allele for that trait. In this case, the dominant allele's phenotype will be expressed, masking the recessive trait. The recessive trait would only be visible if an individual has two copies of the recessive allele.
What is an allele that expresses itself in a hybrid?
A dominant allele is an allele that will always express itself in a hybrid individual, masking the expression of a recessive allele. This means that if a dominant allele is present, its trait will be visible in the phenotype of the organism.
What is a trait that appears only if an organism has two factors for the traits?
A trait that appears only if an organism has two factors for that trait is known as a recessive trait. Recessive traits are expressed phenotypically only when an individual has two copies of the recessive allele, one inherited from each parent. If an organism has one dominant allele and one recessive allele, the dominant trait will be expressed instead. This concept is a fundamental aspect of Mendelian genetics.
Which of Mendel's laws states that only one parental allele for each trait is included in a sex cell?
Mendel's law of segregation states that only one allele for each gene is passed into an organism's gametes. This means that each parent contributes one allele for a particular trait to their offspring.
Is an allele that produces a trait in the heterozygous condition recessive?
No. A recessive allele will not be expressed phenotypically in the heterozygous state. A recessive allele can only be expressed phenotypically in the homozygous state.
What does it mean if a trait or allele is resevive?
A recessive trait or allele is one that is only expressed when an individual has two copies of it, one inherited from each parent. In the presence of a dominant allele, the recessive allele's expression is masked.
A hybrid flower would have the genotype?
A hybrid flower could have a genotype that includes a combination of dominant and recessive alleles for certain traits. For example, a hybrid plant may have a genotype like RrYy, indicating it carries one dominant allele for one trait and one recessive allele for another.
What is an allele that produces a trait in the heterozygous condition called?
An allele that produces a trait in the heterozygous condition is called dominant. This means that only one copy of the allele is needed to express the trait.
Why wouldn't you see a recessive trait?
You wouldn't see a recessive trait if an individual has one dominant and one recessive allele for that trait. In this case, the dominant allele's phenotype will be expressed, masking the recessive trait. The recessive trait would only be visible if an individual has two copies of the recessive allele.
What is an allele that expresses itself in a hybrid?
A dominant allele is an allele that will always express itself in a hybrid individual, masking the expression of a recessive allele. This means that if a dominant allele is present, its trait will be visible in the phenotype of the organism.
Describes a trait or an allele that is expressed only when two of the alleles for the saame characteristic are inherited?
A trait or allele that is only expressed when two alleles of the same type are inherited is called recessive. This means that the individual must inherit two copies of the recessive allele to exhibit the trait. If an individual inherits one dominant allele and one recessive allele for a trait, the dominant allele will be expressed.
Recessive allele different from dominate allele?
You need two recessive alleles to get their trait, but only one dominant allele to get that trait. A dominant allele basically overrides a recessive one if they are together, but the recessive gene can show up in offspring.
How Dominant allele different from recessive allele?
You need two recessive alleles to get their trait, but only one dominant allele to get that trait. A dominant allele basically overrides a recessive one if they are together, but the recessive gene can show up in offspring.
How can an organism have two different alleles for one trait but show one observable trait?
One allele would be dominant and the second allele would be recessive, so the organism would show only the dominant trait.
How does a dominant trait affect the phenotype of an organism?
If the the trait is controlled by only one allele and the allele is completely dominant then once inherited the offspring with exhibit that phenotype
Why is it that a person with an allele for a particular trait may not have a phenotype that shows the trait?
a dominant allele will express its trait , as well as be carried by the person. the word carrier is commonly used for a person who bears an allele which does not express itself(i.e. a recessive gene).
