      Non-Mendelian Genetics Practice Packet Most genetic traits have a stronger, dominant allele and a weaker, recessive allele. In an individual with a heterozygous genotype, the dominant allele shows up in the offspring and the recessive allele gets covered up and doesn’t show; we call this complete dominance.
