``Selection in Genetics,'' by Brindell Horelick and Sinan Koont, UMAP 70. This module introduces genetic terminology and basic results about genotype distribution in successive generations. A recurrence relationship is obtained from which the nth-generation frequency of a recessive gene can be determined. Calculus is used to derive a technique for approximating the number of generations required for this frequency to fall below any given positive value.

In Projects 2–5, complete the requirements of the designated UMAP module (see enclosed CD for UMAP modules).
