PTC, or phenylthiocarbamide, is a chemical that, to humans, either tastes bitter or has no taste at all. The ability to taste the bitterness of PTC is controlled by a single gene that codes for a bitter taste receptor on the tongue. Tasters, or individuals that can taste the bit- terness of PTC, have at least one copy of the dominant allele, T. Nontasters, or individuals who cannot taste the bitterness of PTC, must have two copies of the recessive allele, t. The numbers of tasters and nontasters in the human population are shown in the table below. A B Phenotype с Tasters Select all that apply - There are 2 correct options. D Nontasters Total If the population is in Hardy-Weinberg equilibrium, which of the following identifies the correct genotype frequencies for the population?

Inheritance and Mendelian Genetics

Inheritance means the passing of traits to offspring from parents. These traits could be passed either through asexual reproduction or sexual reproduction. The offspring receives the genetic material from the parents. Mendelian inheritance is a certain biological inheritance that follows the rules and principles laid down by Gregor Mendel in 1865. The initial hypothesis was considered wrong, but other inheritance theories modified the concept of inheritance and thus genetics.
