If the treatment is successful, the new gene will make a functional protein.

If a heterozygote mates with another heterozygote, there is 75 % chance passing the gene on and only a 25 % chance that the gene will be displayed.

If she mated with a man with haemophilia ( another carrier ) there would be a 75 % chance of passing on the gene.

If the treatment is successful, the new gene will make functional protein to treat a disease.

If a siRNA is designed to match the RNA copied from a faulty gene, then the abnormal protein product of that gene will not be produced.

If a mutation occurs within a gene, the new allele may affect the trait that the gene controls, altering the phenotype of the organism.

If an upregulated gene is observed by an abundance of mRNA on the northern blot the sample can then be sequenced to determine if the gene is known to researchers or if it is a novel finding.

. If the gamodeme is very large ( theoretically, approaching infinity ), and all gene alleles are uniformly distributed by the gametes within it, the gamodeme is said to be panmictic.

If the TP53 gene is damaged, tumor suppression is severely reduced.

If researchers were trying to initially determine the chromosomal location of a particular disease gene, they would analyze the DNA of members of a family afflicted by the disease, and look for RFLP alleles that show a similar pattern of inheritance as that of the disease ( see Genetic linkage ).

If the gene encoding the protein can be identified it is currently much easier to sequence the DNA and infer the protein sequence.

For example, in a negative feedback loop, the transcription factor acts as its own repressor: If the transcription factor protein binds the DNA of its own gene, it will down-regulate the production of more of itself.

If a mutation occurs in the second copy of the VHL gene, the cell will have no working copies of the gene and will produce no functional VHL protein.

If searching for microsatellite markers in specific regions of a genome, for example within a particular exon of a gene, primers can be designed manually.

If the way that DNA is wrapped around the histones changes, gene expression can change as well.

If a family has a dominant gene for deafness it will persist across generations because it will manifest itself in the offspring even if it is inherited from only one parent.

If a family had genetic hearing impairment caused by a recessive gene it will not always be apparent as it will have to be passed onto offspring from both parents.

If testing shows that parent is a CFTR gene mutation carrier, the other parent is tested to calculate the risk that their children will have CF.

If the karyotype is 46, XY, testes develop due to the influence of the Y chromosome ’ s SRY gene.

If the circumstances are faced frankly it is not reasonable to expect this to be true.

If his dancers are sometimes made to look as if they might be creatures from Mars, this is consistent with his intention of placing them in the orbit of another world, a world in which they are freed of their pedestrian identities.

If a work is divided into several large segments, a last-minute drawing of random numbers may determine the order of the segments for any particular performance.

If they avoid the use of the pungent, outlawed four-letter word it is because it is taboo ; ;

If Wilhelm Reich is the Moses who has led them out of the Egypt of sexual slavery, Dylan Thomas is the poet who offers them the Dionysian dialectic of justification for their indulgence in liquor, marijuana, sex, and jazz.

If he is the child of nothingness, if he is the predestined victim of an age of atomic wars, then he will consult only his own organic needs and go beyond good and evil.

If it is an honest feeling, then why should she not yield to it??

If he thus achieves a lyrical, dreamlike, drugged intensity, he pays the price for his indulgence by producing work -- Allen Ginsberg's `` Howl '' is a striking example of this tendency -- that is disoriented, Dionysian but without depth and without Apollonian control.

If love reflects the nature of man, as Ortega Y Gasset believes, if the person in love betrays decisively what he is by his behavior in love, then the writers of the beat generation are creating a new literary genre.

If he is good, he may not be legal ; ;

If the man on the sidewalk is surprised at this question, it has served as an exclamation.

If the existent form is to be retained new factors that reinforce it must be introduced into the situation.

If we remove ourselves for a moment from our time and our infatuation with mental disease, isn't there something absurd about a hero in a novel who is defeated by his infantile neurosis??

If many of the characters in contemporary novels appear to be the bloodless relations of characters in a case history it is because the novelist is often forgetful today that those things that we call character manifest themselves in surface behavior, that the ego is still the executive agency of personality, and that all we know of personality must be discerned through the ego.

If he is a traditionalist, he is an eclectic traditionalist.

If our sincerity is granted, and it is granted, the discrepancy can only be explained by the fact that we have come to believe hearsay and legend about ourselves in preference to an understanding gained by earnest self-examination.

If to be innocent is to be helpless, then I had been -- as are we all -- helpless at the start.

If one takes the experimentally observed flow around an airfoil as a starting point, then lift can be explained in terms of pressures using Bernoulli's principle and conservation of mass.

If the predicted half-life falls into an experimentally accessible range, such isotopes have a chance to move from the list of stable nuclides to the radioactive category, once their activity is observed.

If we assume that there is in fact no experimentally detectable difference in these " exchange macrostates " available, then using the entropy which results from assuming the particles are indistinguishable will yield a consistent theory.

If there is an experimentally verified correspondence between a conceptual system and a physical system then that conceptual system models the physical system.

If the theory has one point in its favour it is that every step can be tested experimentally, and that many steps have already received positive support from such testing.
