ABSTRACT

A dictionary of terminology for reference in modern genetics is presented. Attempt is made to define and standardize genetic terminology. The author includes the older terminology in genetics, to enable the student to read and understand early literature in genetics, which contains terminology not in present day use. Included terms embrace those in common use in cytology, animal breeding and evolution. Appendixes are included of useful formulas; coefficients of expansion: (1 + X)n for values of n, and 2n and 4n for values of n; distributions of X2; genotypes expected in backcrosses and in F2s; tables of percentages in homozygotes; rates of elimination of donor genotype in backcrossing, and international rules for symbolizing genes and chromosome aberrations. An excellent bibliography is included.

This dictionary should be an excellent aid to those who are working directly in genetics and particularly for new students of the subject.
