What are genetic principles?

Genetic principles are the rules or standards governing the biological phenomenon of heredity , the transmission of characteristics from parents to offspring via information encoded biochemically using DNA , in units called genes.

What is Mendel’s principle of Dominance?

Mendel’s law of dominance states that in a heterozygote, one trait will conceal the presence of another trait for the same characteristic. Rather than both alleles contributing to a phenotype, the dominant allele will be expressed exclusively.
