What else can I help you with?
Dominance resulting in the blending of alleles?
Incomplete dominance
What type of allele dominance occurs when both the alleles are active and expressed?
When both the alleles are expressed, it is called co-dominance or mixed dominance.
When are both alleles expressed in offspring?
Both alleles are expressed in offspring when neither allele is dominant over the other, resulting in co-dominance. This means that both alleles are simultaneously expressed in the offspring's phenotype.
What does the principle of dominance state?
Basically, it states there are two forms of a gene called alleles, heterozygous in this case, and one allele masks the expression of the other allele. This is simplified, as it can get complex with co-dominance and partial dominance.
What type of allele dominance occurs when both alleles are active and expressed?
Either Co-dominance, where different parts of the organism display the different alleles (i.e. red and white flowers), or a combination of the two alleles (i.e. red and white alleles make pink flowers)
Recessive genes will always be masked by dominant genes This is Mendel's principle of?
This is Mendel's principle of dominance. Dominant alleles will always mask the presence of recessive alleles in a heterozygous genotype.
What is the principle of dominance?
The Principle of Dominance states that some alleles are dominant and some alleles are recessive. The dominant trait dominates or presents the expression of the recessive trait. Thus, for round seed: (capital) R - round (small) r - wrinkled RR - pure round Rr - hybrid round rr - pure wrinkled
Dominance resulting in the blending of alleles?
Incomplete dominance
What type of allele dominance occurs when both the alleles are active and expressed?
When both the alleles are expressed, it is called co-dominance or mixed dominance.
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.
When are both alleles expressed in offspring?
Both alleles are expressed in offspring when neither allele is dominant over the other, resulting in co-dominance. This means that both alleles are simultaneously expressed in the offspring's phenotype.
What does the principle of dominance state?

What three principles of heredity did mendel discover?
The inheritance of biological characteristics is determined by individual units known as genes. They are passed from parent to offspring.In cases in which two or more alleles of the gene for a single trait exist, some forms of the gene may be dominant or recessive.In most sexually reproducing organisms, each adult has two copies of each gene- one from each parent. These are segregated from each other when gametes are formed.The alleles for different genes usually segregate independently of one another.
According to the rule of dominance if two different alleles are present is the dominant allele expressed?
the dominant allele is expressed when two (assuming you mean dominant and recessive) alleles are present. however, if the alleles are codominant they are both expressed.
What type of allele dominance occurs when both alleles are active and expressed?
Either Co-dominance, where different parts of the organism display the different alleles (i.e. red and white flowers), or a combination of the two alleles (i.e. red and white alleles make pink flowers)
What kind of dominance its it called when bother alleles are blended and expressed?
incomplete dominance
What is it called when the presence of two different alleles result in an intermediate phenotype?
It is called codominance or incomplete dominance.
