When bacterial populations have these resistant subgroups, treatment with β-lactam can result in the resistant strain becoming more prevalent and so more virulent.

When looking for a long-term partner more conventional altruism may be preferred which may indicate that he is also willing to share resources with her and her children while when looking for a short-term partner heroic risk-taking, which may be costly signal showing good genes, may be more preferable.

When instead the wild type trait is expressed, the positions are said to belong to distinct cistrons / genes.

When genes are inserted, they usually come from a different species, which is a form of horizontal gene transfer.

When these regulatory elements control the imprinting of one or more genes, they are known as imprinting control regions ( ICR ).

When proteins are generated from intron-containing genes, RNA splicing takes place as part of the RNA processing pathway that follows transcription and precedes translation.

When the populations come back into contact, they have evolved such that they are reproductively isolated and are no longer capable of exchanging genes.

When the transposable elements lack additional genes, they are known as insertion sequences.

When injected into plants, these proteins can enter the nucleus of the plant cell, bind plant promoter sequences, and activate transcription of plant genes that aid in bacterial infection.

When a cell switches to the biofilm mode of growth, it undergoes a phenotypic shift in behavior in which large suites of genes are differentially regulated.

When genome complexity is relatively high, like in the case of human genome, not only different genes, but also inside one gene there are gaps of introns to protect the entire coding segment to minimise the changes caused by mutation.

When Waddington coined the term the physical nature of genes and their role in heredity was not known ; he used it as a conceptual model of how genes might interact with their surroundings to produce a phenotype.

When the inducer binds the receptor, it activates transcription of certain genes, including those for inducer synthesis.

When embryonic ectodermal cells are cultured at low density in the absence of mesodermal cells they undergo neural differentiation ( express neural genes ), suggesting that neural differentiation is the default fate of ectodermal cells.

When it occurs by itself, it is associated with autosomal dominant mutations in single genes, i. e. it is not a multifactorial trait.

When two genes are close together on the same chromosome, they do not assort independently and are said to be linked.

When chromosomes and genes are damaged, often through rearrangement, this control is lost.

; Comparison: When working with genes, BLAST can locate common genes in two related species, and can be used to map annotations from one organism to another.

When the DNA of tumor cells is analyzed using electrophoresis, a clonal band can be demonstrated, since identical IgH genes will move to the same position.

When Ras is ' switched on ' by incoming signals, it subsequently switches on other proteins, which ultimately turn on genes involved in cell growth, differentiation and survival.

When the F genes become integrated into the chromosome, the cell is said to be Hfr ( high frequency of recombination ).
