Concepts in this unit
T-012
Mendel's law of segregation
Paired alleles separate into different gametes.
T-013
Mendel's law of independent assortment
Genes on different chromosomes are inherited independently.
T-014
The dihybrid cross
Predicting the 9:3:3:1 ratio of two traits.
T-015
Genetic linkage and recombination
Nearby genes tend to be inherited together.
T-016
Sex linkage
Inheritance of genes carried on the sex chromosomes.
T-177
The Nernst potential for a single ion
Let a membrane separate two well-stirred aqueous compartments, an inside and an outside, and let it be permeable to exactly one ionic species S of valence...
T-178
The Goldman-Hodgkin-Katz equation
Permeability-weighted concentrations set the membrane voltage: the log of the weighted sum ratio is the potential at which the net ionic current is zero.
