What is a genetic factor that is blocked by the presence of a dominant factor?
A genetic factor that is blocked by the presence of a dominant factor is known as a recessive allele. In a heterozygous genotype, where one allele is dominant and the other is recessive, the dominant allele's traits will be expressed while the recessive allele's traits are masked. For example, in pea plants, the allele for tall stems (dominant) will override the allele for short stems (recessive), resulting in all offspring displaying the tall phenotype.
A genetic factor that blocks another genetic factor is called what?
A genetic factor that blocks the expression of another genetic factor is called a "dominant" allele. In genetics, when one allele is dominant over another, it masks the effect of the recessive allele, preventing it from being expressed in the phenotype. This interaction is a fundamental principle of Mendelian inheritance.
What did Mendel mean by a dominant factor?
Mendel meant that a dominant factor is a gene that expresses its trait in an individual when present with the corresponding recessive gene. The dominant allele masks the expression of the recessive allele in a heterozygous individual.
What factor determines whether the frequency of the new allele will increase?
Which factor might determine whether the frequency of the new allele will increase in a population where a mutation occurs?
What is a recessive factor?
A recessive factor refers to a genetic trait that is masked by a dominant factor in an organism's genotype. For a recessive trait to be expressed phenotypically, an individual must inherit two copies of the recessive allele, one from each parent. In contrast, if at least one dominant allele is present, the dominant trait will be expressed. This concept is fundamental in Mendelian genetics, illustrating how traits are passed from parents to offspring.

A factor that seems to disappear?
a recessive allele

What is a synonym for allele?
allelomorph, gene, cistron, factor
What the term factor mean in Mendel first law?
allele
What did Mendel mean by a dominant factor?
Mendel meant that a dominant factor is a gene that expresses its trait in an individual when present with the corresponding recessive gene. The dominant allele masks the expression of the recessive allele in a heterozygous individual.
What factor determines whether the frequency of the new allele will increase?
Which factor might determine whether the frequency of the new allele will increase in a population where a mutation occurs?
Principle states that one factor in a pair may prevent the other factor in the pair from being expressed?
This principle is called the principle of dominance. It explains that in a pair of alleles, the dominant allele will be expressed over the recessive allele. So, the dominant factor will prevent the recessive factor from being expressed in the phenotype.
What factor would cause a mutation that would cause an allele frequency to increase?
An increase in allele frequency can occur due to factors such as genetic drift, gene flow from other populations, natural selection favoring that allele, or a genetic mutation that confers a selective advantage.
What is an allele and what is a nasty allele?
Allele is word used by Mendel for counter parts of an elementon later called factor and renamed as gene e.g. T and t are alleles for a gene that controls height in pea plant .Nasty allele is not biological term .Note word elementon is technical term used by Mendel , it is not element used in Chemistry .
What is allele masked by the dominant allele?
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).
Allele that prevents the expression of a recessive allele?
A dominant allele
