Sentence examples for mating of heterozygotes from inspiring English sources

The APL1A1 homozygotes must certainly be generated each generation by the mating of heterozygotes, but due to their low frequency their fate and potential infection phenotype remains an open question.

Bax deficient mice (Bax−/−) were obtained by mating of heterozygotes.

Specific characterization of the CCKAR gene was based on individuals produced by the mating of heterozygotes at a three-loci haplotype covering the region of the CCKAR gene ch4snp-32-183-65476-S-1, CCKAR_MnlI, and ch4snp-131-132-4046-S-2.

Upon completion of these 8 backcrosses, brother-sister mating of two heterozygotes created the desired chromosomal regions homozygous for the donor's alleles and yielded offspring in the ratio M1 2M1M2 1M2M2.

Embryos were obtained from the mating of Sall1 heterozygote (Sall1+/−) animals, maintained on a C57BL/6J background, and genotyped as previously described (Nishinakamura et al., 2001).

Early work on Drosophila spp. revealed that flies heterozygous for certain inversions showed superior fitness and developmental homoeostasis compared with their homozygote counterparts (Dobzhansky and Wallace 1953; Spiess and Langer 1966), which was correlated to increased courting and mating frequency of heterozygote males (Brncic and Koref-Santibanez 1964).

If, for example selection is in operation, negative values are expected (i.e. excess of heterozygotes) if mating of relatives is practiced, positive values are expected (i.e. lack of heterozygotes).

To further probe the identity of nuclear K-Ras, we have generated K-Ras knockout (K-ras−/−) embrionary fibroblasts by mating of K-ras+/− heterozygote mice.

Secondly, positive assortative mating will tend to decrease the proportion of heterozygotes in the population, thus increasing the genotypic variance.

Primary murine embryonic fibroblasts (MEF) of all three genotypes were prepared from day 13 embryos following mating of male and female 5T4 heterozygote C57BL/6 transgenic mice by methods previously described [55].

There are three possible explanations for the deficiency of heterozygotes in the first generations selection, assortative mating and inbreeding.
