How do you explain the principle of dominance?

Answer 1

Genetic dominance?

One gene is dominant over the other gene in the chromosome pair by having it protein product made totally at the expense of the recessive gene, or the protein product dominates production.

For instance, blue eye color is recessive to brown eye color. You have two alleles ( different molecular form of the same gene ) in this case; one from one parent and one from the other parent. Only the brown allele expresses and is called dominant then.

Answer 2

The Principle of Dominance explains that if there is both a dominant and a recessive allele in an organism, the dominant gene will be the one observed. For example, pea plant flowers are either white or purple. If a pea plant had both a white color allele and a purple color allele, only the purple will be shown. Therefore, the purple is dominant. Another example is eye color in humans. The brown eye color is dominant to the blue eye color. Therefore, the brown eyes gene will mask the blue eyes gene.

Answer 3

The principle of dominance in genetics states that one allele can mask the expression of another allele in a heterozygous individual. This means that one allele (dominant) will determine the phenotype, while the other (recessive) allele will have no effect on the phenotype. This principle was discovered by Gregor Mendel and is a key concept in understanding inheritance patterns.
