Question: Assume you are provided an isolated muscle with its motor nerve intact. The preparation allows you to make electrophysiological measurements from the nerve and muscle as well as mechanical measurements of muscle contraction. You observe that if Drug A is added to the fluid bathing the preparation, the peak tension […]

Punnett squares are convenient ways to represent the types and frequencies of gametes and progeny in experimental crosses. This Punnett square shows the results of a Gg x Gg cross to form F2 progeny. Use your understanding of Mendel’s Law of Segregation and the rules of probability to complete the […]

Q. 1. Alleles might be explained as: a. similar forms of two different loci b. alike forms of two different genes c. Alternative forms of a single gene d. Alternative forms of two different loci 2. A mutation which produces a change from wild type to an abnormal phenotype is […]

Question: The OMIM description on “Genetic Mapping of Alkaptonuria” can be interpreted to say: The alkaptonuria gene was genetically mapped to 3q2 at 16cM away from the sucrase-isomaltast deficiency gene in inbred families with some members manifesting both conditions. Statistically the alkaptonuria causing mutant gene and the sucrase-isomaltase deficiency-causing mutant gene […]
