*undoubtedly they can, just on principle, but two factors mitigate against it mattering, they have many kits, and those with double recessive lethal genes simply won't develop or die at birth and so on.

This typically works by disrupting or removing the lethal gene during the cloning process, and unsuccessful clones where the lethal gene still remains intact would kill the host cells, therefore only successful clones are selected.

The sex-lethal gene is often abnormally expressed in male hybrids from " D . melanogaster " mothers as a result of re-localization of the male-specific complex to the X chromosome, which contributes to the male sterility.
25.
The disorder is caused by a genetic defect inherited from both parents, and most, like the Godeks, have no idea that they are carriers of a lethal gene until they give birth to a seriously ill child.

An example of a non lethal gene deletion in a sample metabolic network with fluxes shown by the weight of the reaction lines as calculated by FBA . Here the flux through the objective function is halved but is still present.

An example of a lethal gene deletion in a sample metabolic network with fluxes shown by the weight of the reaction lines as calculated by FBA . Here there is no flux through the objective function, simulating that the pathway is no longer functional.

Recent studies have shown that a critical gene for gender determination in " Drosophila " known as the sex-lethal gene is highly misregulated in " D . melanogaster " and " D . simulans " hybrids, compared with the degree of misregulation of non-sex biased genes studied.

Three features characterize the " t " region : suppression of recombination over the entire length of a complete " t "-haplotype; segregation distortion ( " t " / + males transmit the " t "-chromosome into more than 90 percent of their progeny ); and frequent presence of homozygous lethal genes.
