What allele covers up or dominates the other trait?
The dominant allele covers up or masks the expression of the recessive allele in a heterozygous individual. The dominant allele is typically represented by an uppercase letter, while the recessive allele is represented by a lowercase letter.
What Does a particular trait result from the expression of a single gene?
Huntington's disease is a perfect example of a single gene trait. A mutation in this allele causes Huntington's disease in later life. A dominant trait. Widows peak us another. Any gene that controls the total expression of a trait is an allele defined as a single gene trait.
What form of gene that always shows even in the presence of recessive allele?
The dominant gene always shows up in the presence of a recessive allele. This is because the dominant gene masks the expression of the recessive gene when both are present in an individual's genetic makeup.
What gene pair is made up of one dominant allele and one ressecive allele?
A heterozygous condition resulting in the dominant genes expression in the phenotype.
What is the multiple allele system?
The multiple allele system refers to a genetic system where a particular gene has more than two alleles present within a population. Each individual carries a maximum of two alleles for a gene, but the population as a whole may have multiple alleles. An example of this is the ABO blood group system in humans.
What allele covers up or dominates the other trait?
The dominant allele covers up or masks the expression of the recessive allele in a heterozygous individual. The dominant allele is typically represented by an uppercase letter, while the recessive allele is represented by a lowercase letter.
What is the capacity of one allele to suppress the expression of a contrastingly recessive gene?
dominance
Capacity of one allele to suppress the expression of contrasting recessive gene?
dominance
Is allele a gene?
yes an allele is a gene

The dominant gene always shows up in the presence of a recessive allele. This is because the dominant gene masks the expression of the recessive gene when both are present in an individual's genetic makeup.
Which form of gene pair is expressed when both dominant and recessive are present?
In a situation where both a dominant and recessive allele are present in a gene pair, the dominant allele will be expressed phenotypically. The presence of a dominant allele overrides the expression of the recessive allele.
What gene pair is made up of one dominant allele and one ressecive allele?
A heterozygous condition resulting in the dominant genes expression in the phenotype.
What is the multiple allele system?
The multiple allele system refers to a genetic system where a particular gene has more than two alleles present within a population. Each individual carries a maximum of two alleles for a gene, but the population as a whole may have multiple alleles. An example of this is the ABO blood group system in humans.
What is a member of a gene pair that determines a specific trait?
An allele is one of the possible variations of a gene that can determine a specific trait. Alleles come in pairs, with one allele inherited from each parent, and the combination of alleles present determines the expression of the trait.
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 is null allele?
A null allele is a mutant copy of gene that completely lacks that gene's normal function. This can be the result of the complete absence of the gene product (protein, RNA) at the molecular level, or the expression of a non-functional gene product. At the Phenotypic level, a null allele is indistinguishable from a deletion of the entire locus.
