In the context of genetics and behavior,the dominant-recessive genes principle implies that the dominant gene prevents the recessive gene from expressing its instructions.

Question

Quizplus · Accepted Answer

The dominant-recessive genes principle is based on the fact that dominant genes mask the expression of recessive genes in a heterozygous individual. In other words, if an individual inherits a dominant allele from one parent and a recessive allele from the other parent, the dominant allele will determine the individual's phenotype (observable traits), while the recessive allele will be hidden or suppressed. Therefore, the answer is True, as the dominant gene prevents the recessive gene from expressing its instructions in a heterozygous genotype.
