Question 5 You are studying a species of tree frog with skin that produces different toxins based on the genotype of the Tox locus. Alleles E and N are codominant. Individuals homozygous for E are emetic (eating them causes vomiting), while individuals homozygous for N produce a neurotoxin. Heterozygotic frogs produce a toxin with both qualities. At the La Selva Biological Station in Costa Rica, you collect frogs from the field site and test them in the lab. You find 93 neurotoxic frogs, 113 emetic frogs, and 12 frogs with both toxic qualities. Using the Hardy-Weinberg equilibrium equation, what are the expected numbers of frogs given their genotypes at the Tox locus? A) 45 NN, 108 NE, 65 EE B 93 NN, 12 NE, 113 EE C) 324 NN, 446 NE, 154 EE 198 N, 238 E Last saved

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.
