STUDIES OF NATURAL POPULATIONS OF MUS. I. BIOCHEMICAL POLYMORPHISMS AND THEIR BEARING ON BREEDING STRUCTURE.

摘要: Although the house mouse (Mus musculus L.) has received considerable attention from both ecologist and geneticist, very little information is available about genetic aspects of natural Mus populations. Reasons for paucity such are without doubt numerous. One which became obvious early in current study that most variants known were discovered studied mice bred laboratory, under highly protective conditions. These same do not exist with any high frequency more stringent conditions environment so value investigations Only three systems have given parameters populations musculus: (1) agouti locus (Philip, 1938; Engels, 1948), (2) T (Dunn, 1957a, b; Dunn Suckling, 1956; Lewontin Dunn, 1960) (3) discontinuous skeletal (Gruneberg, 1952; Weber, 1950; Deol, 1958; Berry, 1963). Of these, first relatively straightforward, some evidence, unfortunately limited conflicting, breeding structure mouse. The likewise this respect because number complications involved (e.g., homozygous lethality, transmission ratio t-bearing sperm heterozygous males, vari-
