The final duplication in the mutantallele is underlined. One of the spores carries a mutantallele with a structure showing that a duplication in one chromatid had been transferred to a homologous chromatid. It is possible that the locus randomly selected for mutation is homozygous for the mutantallele, resulting in a failure of mutation. Previous work has shown that the mutantallele is dominant and maps at a new locus on chromosome 1, between fuzzy (fz) and leaden (ln). Thus, each control sample was also analyzed for heteroduplex formation with the wild-type and with the mutantallele from subject 4041. Positive selection is an evolutionary process of selecting an advantageous mutantallele. It assumes only two alleles and ignores mutation, other than the unique event that created the mutantallele. This strategy is in contrast to the reverse genetic approach that starts with a known mutantallele and evaluates possible mutant phenotypes. We show that this variegation is attributable to an unstable mutantallele of the gene encoding dihydroflavonol-4-reductase, one of the enzymes required for anthocyanin biosynthesis. Anticipation generally occurs when the mutantallele is inherited through the paternal line. Recessive or partially recessive deleterious mutations should be ' purged ' from such populations, because mutantallele frequencies may be reduced more effectively by selection than in large randomly mating populations. A similar variation was observed in tetraploids when we assumed that the mutantallele has a marked deleterious effect only if present in two or more copies (duplex mutation). Heterozygous carriers (individuals who inherit one mutantallele) show abnormal enzyme activity, but manifest no disease symptoms.

The condition is an autosomal recessive disorder, and it is therefore usually necessary for an affected individual to receive the mutantallele from both parents.

In contrast, a female must inherit two mutant alleles, a less frequent event since the mutantallele is rare in the population.

However, meiotic instability could result in a dynamic mutation that increases the number of repeats in offspring inheriting the mutantallele.
