According to Mendel's law of segregation, the expected outcome of a cross (mating) between a normal (homozygous) mouse and a heterozygous mutant mouse would be a litter in which one-half of the pups had spotted tails and the other half did not.
To test the farming performances of wild sea bass populations, we produced a partial diallel cross mating scheme, using sires originating from North Atlantic (NAT), South Atlantic (SAT), West Mediterranean (WEM), North-East Mediterranean (NEM) and South-East Mediterranean (SEM).
Fig. 4B shows the results of genotyping of pups resulting from inter cross mating.
The litter was produced by cross mating two dogs that previously had produced Col3GP affected offspring.
After cross mating, Ppp2ca fl/fl /AlbCre + (i.e., knockout, KO), Ppp2ca fl/fl and AlbCre + were generated and used in the experiments.
In the reciprocal cross, mating occurrences were not different than in the parental strains, but mating duration was about double, again with the male having observed difficulty disengaging from the female.
One is to prevent cross-mating between different species, an occurrence that usually results in the waste of the eggs and sperm.
Using mating crosses, mating types were assigned to ten isolates of the heterothallic fungal species Ophiostoma quercus.
Field studies in Mali have shown that strictly sympatric and synchronously breeding populations of M and S forms cross-mate at a rate of only ca. 1% [15].
First, cross-mating between two heterozygous clones of the Florida strain resulted in 31% obligatory parthenogenetic clones (Fig. 1, clones 4 and 5 of the Florida strain).
Nested association mapping (NAM) population derived from a multiple-cross mating design sharing one common parent was therefore proposed to enable high power and high resolution through joint linkage and association analysis, and to provide a broader genetic resource for quantitative trait analysis [4].
