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.

The principle of dominance states that one allele in a gene pair can mask the expression of another allele, resulting in the dominant allele being expressed in the phenotype. This means that only one copy of the dominant allele is needed for it to be observed, overriding the expression of the recessive allele when present.

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 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.


The principle or law of heridity which states that only the dominant trait can be seen in an organism that contains in genes a pair of contrasting traits is called?

This principle is known as the law of dominance or dominant-recessive inheritance. In this case, the dominant trait will be expressed, masking the recessive trait.

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
