About 80% of the human population can taste the chemical phenolthiocarbamide (PTC), while the other 20% can’t. This characteristic is governed by a single gene with two alleles, a tasting allele and a nontasting allele. What does this statistic tell us about which allele (tasting or non-tasting) is dominant?
Tasting gene is dominant
