Protocol describes a method for assembling aggregates between diploid embryos. If embryos from a heterozygous mutant intercross are aggregated with wild-type embryos, the resulting chimeras can be used for analyzing mutant phenotypes. - [Read Assembling Aggregates between Diploid Embryos Protocol]
Genotyping Protocol: MMRRC 425. Assay Type: PCR - can distinguish heterozygous animals from homozygous animals. DNA Extraction: DNA from tail snips was ... - [Read Genotyping Protocol: T1320 mouse]
Protocol for spore germination. This procedure is typically used for the isolation and preparation of spores from a diploid strain heterozygous for a marked disruption (e.g., yfg1::his3+) Inoculation of the spore population into minimal medium lacking the nutritional supplement corresponding to the disruption marker (e.g., minimal medium lacking histidine) allows only the disruption spores to germinate. - [Read Spore Germination Protocol]
Alfalfa is an outcrossing species, cultivars consist of populations rather than individual homozygous or
inbred lines. After only two cycles of self-pollination, severe inbreeding depression eliminates selfed
individuals from populations. To obtain sufficient plant material of relative genetically uniformity (these
plants will still necessarily be heterozygous) for experimental purposes, it may be necessary to propagate a
single individual or clone. - [Read Vegetative Propagation of Alfalfa by Stem Cuttings]
