The best known, although not the most common, pattern of allele variation is the simple dominant-recessive gene pair.

Question

Quizplus · Accepted Answer

This statement is true. The dominant-recessive gene pair is a well-known pattern of inheritance in which one allele (the dominant allele) masks the effects of the other allele (the recessive allele) in a heterozygous individual. However, there are many other patterns and modes of inheritance that involve more than one gene or allele, such as co-dominance, incomplete dominance, polygenic inheritance, and epistasis.
