Question
Chapter 24.3, Problem 13COQ
Summary Introduction
To explain:
How genes affecting a polygenic trait are located by using QTL mapping.
Introduction:
Polygenic inheritance is an exception to Mendel’s laws. Polygenic traits have wide variation in them. These traits are regulated by more than one gene. Height is an example of a polygenic trait, which is controlled by three genes having six alleles. If a person is dominant in all the alleles, then height would be very tall. Another example of polygenic trait is skin color in people.

- 3. A promising new drug is being evaluated in human trials. Based on preliminary human tests, this drug is most effective when plasma levels exceed 30 mg/L. Measurements from preliminary tests indicate the following human pharmacokinetic parameter values: t1/2,elim = 4.6hr, t1/2,abs = 0.34hr, VD = 0.29 L/kg, Foral = 72%. Based on these parameters, estimate the following if a 49 kg woman were to receive a 1000mg oral dose of this drug: (a) Estimate the plasma concentration of the drug at 1hr, 6 hr, and 20hr after taking the drug ( Concentration estimate) (b) Estimate the time for maximum plasma concentration (tmax). (c) Estimate the maximum plasma concentration (Cmax). (d) Estimate the time at which the plasma level first rises above 30 mg/L. (Note this is a trial and error problem where you must guess a time, plug it into the concentration equation, and determine if it is close to 30 mg/L.
