Recombination in Species Crosses.

N THE field of mathematics there are numerous problems difficult to I solve with finite numbers which become relatively simple when the concept of infinity is introduced, Similarly, though the genetics of species crosses is obscure when considered in terms of single factors, i t seemed possible that i t might be illuminated if one attempted to consider the total recombination of specific differ...

Comparisons of Specific Crosses

Specific crosses resulting in 305 litters sired by Duroc, Spot or Hampshire boars out of Landrace, Duroc-Landrace or YorkshireLandrace sows were evaluated for preweaning and postweaning performance. Duroc-sired litters were heavier (P<.05) at 21 days postfarrowing than Spotor Hampshiresired litters. Hampshire-sired litters were heavier (P<.05) at birth than Spot-s i red litters. Litters from cr...

Partial Diallel Crosses

A diallel cross is a set of all possible matings between several genotypes, which may be individuals, clones, homozygous lines, etc. Such crosses are used to estimate general and specific combining abilities of lines and crosses respectively. For ‘n’ inbreed lines, the possible F1’s are n(n–1)/2, which are to be tested in a suitably replicated randomized design. With facilities available for te...

Reciprocal Crosses in Streptomyces Coelicolor.

interaction of two complementary growth-factor dependent mutants, i.e., Tzp lemen ta ry auxotrophs, of Streptomyces coeticolor to form grovvth-factor independent progeny, i.e., prototrophs, was interpreted as gene recombination by SERMO~TI and SPADA-SERMONTI (1955) and by BRAENDLE and SZ+BALSKI (1959yi but as heterokaryosis by BRADLEY (1957). The former workers concluded that gene recombination...
