Quizplus · Accepted Answer

Four dominant and four recessive is the most common inheritance pattern, as it allows for a range of possible genotypes and phenotypes. This pattern follows the principles of Mendelian genetics, where two copies of a gene can either be homozygous dominant, heterozygous, or homozygous recessive. This results in a 1:2:1 ratio of genotypes and a 3:1 ratio of phenotypes in offspring.
