61 Capecchi, Mario R.Targeted disruption of the even-skipped gene, evx1, causes early postimplantation lethality of the mouse conceptus.Implantation within the mammalian uterus elicits dramatic changes in the growth, differentiation, and morphogenesis of the conceptus. This process is interrupted in mice carrying a targeted disruption of the murine evx1 gene, a homolog of the Drosophila even-skipped (eve) gene. Upon implantation, pr...Extraembryonic; Homozygotes; Drosophila1994-08-15
62 Thomas, Kirk R.; Capecchi, Mario R.Introduction of homologous DNA sequences into mammalian cells induces mutations in the cognate gene.Injection of homologous DNA sequences into nuclei of cultured mammalian cells induces mutations in the cognate chromosomal gene. It appears that these mutations result from incorrect repair of a heteroduplex formed between the introduced and the chromosomal sequence. This phenomenon is termed 'heter...Animals; Cell Line; Drug Resistance, Microbial; Fibroblasts; Mice; Models, Genetic; Neomycin; Plasmids1986-11-06
63 Rogers, Alan R.; Jorde, Lynn B.Ascertainment bias in estimates of average heterozygosityPopulation geneticists work with a nonrandom sample of the human genome. Conventional practice ensures that unusually variable loci are most likely to be discovered and thus included in the sample of loci. Consequently, estimates of average heterozygosity are biased upward. In what follows we descri...Bias (Epidemiology); Biometry; Heterozygote1996-05
64 Capecchi, Mario R.Gene targeting. How efficient can you get?With targeting in Leishmania and Trypanosoma, there are now greater incentives to develop the technology in organisms of intermediate complexity such as Caenorhabditis elegans and Drosophila.
