What type of inheritance that involves one dominant allele and one recessive allele is called?
The type of inheritance that involves one dominant allele and one recessive allele is called simple Mendelian inheritance or complete dominance. In this pattern, the phenotype of the organism will display the trait associated with the dominant allele, while the recessive allele's effects are masked when both alleles are present. An example of this is the inheritance of flower color in pea plants, where purple (dominant) flowers mask the expression of white (recessive) flowers.

What is complte inheritance?
Complete inheritance refers to a situation where one allele is completely dominant over another in a gene pair, resulting in the dominant allele always being expressed in the phenotype, while the recessive allele remains hidden. This type of inheritance follows Mendel's laws of inheritance, where dominant traits mask the expression of recessive traits in an individual's phenotype.
How do dominant and reccessive factors interact?
Dominant and recessive factors interact through the principles of inheritance, where dominant alleles mask the effects of recessive alleles in a heterozygous genotype. This means that if an organism carries one dominant and one recessive allele for a trait, the dominant trait will be expressed in the phenotype. Recessive traits only manifest when an individual has two copies of the recessive allele. Thus, the presence of a dominant allele can overshadow the influence of a recessive allele in determining observable characteristics.
What is dominant chromosome?
A dominant chromosome refers to a chromosome that carries a dominant allele, which expresses its trait even when paired with a recessive allele. In genetics, dominant alleles can mask the effects of recessive alleles in a heterozygous organism. This means that if an individual has one dominant allele for a trait, that trait will be expressed, regardless of the presence of a recessive allele. Dominance is a key concept in Mendelian genetics, influencing inheritance patterns.
Does recessive allele is expressed if there is no dominant allele present?
Yes, a recessive allele will be expressed if there is no dominant allele present in the genotype. This is because in the absence of a dominant allele, the recessive allele has the opportunity to be expressed in the phenotype.
When on e allele of a gene masks the presence of the other allele what form is masked?
The recessive allele.
What is it called having a dominate and recessive allele?
Having a dominant and recessive allele is known as Mendelian inheritance, named after Gregor Mendel, the scientist who first described it. In this type of inheritance, the dominant allele masks the expression of the recessive allele in heterozygous individuals.
What is the nature of a relationship in which one allele is completely dominant over another in genetic inheritance?
In a relationship where one allele is completely dominant over another in genetic inheritance, the dominant allele will always be expressed in the phenotype, while the recessive allele will only be expressed if both alleles are recessive. This is known as complete dominance.
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).
What is complte inheritance?
Complete inheritance refers to a situation where one allele is completely dominant over another in a gene pair, resulting in the dominant allele always being expressed in the phenotype, while the recessive allele remains hidden. This type of inheritance follows Mendel's laws of inheritance, where dominant traits mask the expression of recessive traits in an individual's phenotype.

Recessive traits only manifest when an individual has two copies of the recessive allele. Thus, the presence of a dominant allele can overshadow the influence of a recessive allele in determining observable characteristics.
In one allele is dominant to a recessive allele?
In a dominant-recessive allele relationship, the dominant allele will be expressed phenotypically over the recessive allele. This means that even if an organism carries one dominant and one recessive allele for a particular trait, the dominant allele will determine the observable characteristic.
What is it Dominant allele What is a recessive allele?
A genotype in which there are both a dominant and a recessive allele is called heterozygous.
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.
Is a situation in which a dominant allele completely masks a recessive allele for a gene.?
If you have 2 dominant alleles, the gene will be dominant, if you have 2 recessive alleles, the gene will be recessive. But if you have 1 recessive and 1 dominant, the Dominant allele will mask the recessive one.
Does recessive allele is expressed if there is no dominant allele present?
Yes, a recessive allele will be expressed if there is no dominant allele present in the genotype. This is because in the absence of a dominant allele, the recessive allele has the opportunity to be expressed in the phenotype.
Is albinism controlled by a dominant allele or by a recessive allele?
Recessive allele.
