Final answer:
Dominant traits remain dominant when an individual has at least one dominant allele and do not change to recessive with different individuals; they are consistently expressed across different people as long as the dominant allele is present.
Step-by-step explanation:
The question relates to the inheritance of dominant and recessive traits and whether a dominant trait can become recessive in a different individual. The answer to this question is no; dominant traits do not change their expression depending on the person. If an individual has at least one dominant allele for a gene, the dominant trait will be expressed. This expression remains consistent regardless of environmental factors or specific genetic mutations unless there is a significant alteration in the gene's function which is not the general rule.
A dominant trait is one that will manifest in the offspring when at least one dominant allele (a variant of a gene) is present. In contrast, a recessive trait only appears when an individual has two copies of the recessive allele. The Mendelian principles of inheritance maintain that the expression of dominant and recessive traits follows predictable patterns and does not switch between dominance and recessiveness with different individuals.
