β¦ Synopsis
Heterozygotes from matings of the mouse strains YBR/Cv and C3H/As have about 3 times more YBR-amylase than C3H-amylase in the saliva. The determinant for this quantitative effect is located on linkage group XVI close to or within the structural gene for salivary amylase. The quantitative effect is the result of an increase in the rate of synthesis of YBR-amylase, and the determinant is cis acting. Studies of other mouse strains suggest that regulatory genetic elements may modulate salivary amylase production.

The expression of pancreatic amylase in the mouse exhibits pronounced genetic variation. Congenic lines with various amylase complexes on a common C3H/As background have different numbers and forms of isoenzymes. The relative ratio of these isoenzymes may vary, as does the overall production of panc
We have sampled wild chromosomes from two natural populations of Drosophila melanogaster and obtained flies fully homozygous for the second chromosome, the third chromosome, or both, as well as flies heterozygous for one or both wild chromosomes and balancer chromosomes. Rate of embryogenesis (egg l
