Sentence examples for eye mutation from inspiring English sources

In 1911, Thomas Hunt Morgan argued that genes are on chromosomes, based on observations of a sex-linked white eye mutation in fruit flies.

Drosophila pseudoobscura bogotana carrying a white eye mutation were used in the crosses described below, as the white locus is linked to an inversion that distinguishes between D. p. bogotana and D. persimilis.

All three alleles showed a reduced-wing phenotype, suggesting that, as in the eye, mutation of any of these genes reduces compensatory growth in the wing.

For instance, this technique was applied to isolate strains with spontaneous [8], [18], [19] or chemically induced [20] mutations leading to heritable eye mutations and to study acute toxic effects on the eye [18].

The locus near the spreading advantageous eye color mutation loses one of the two alleles initially present, representing a loss of variation near the site of the mutation.

For this, leaky alleles of the white eye color mutation in Drosophila were used.

Along with the distribution data, this strongly suggests that the TG allele of BEH2 is, contains, or is in strong LD with the blue eye causal mutation.

In Drosophila wing or eye epithelia, mutation of ex is sufficient to cause mild tissue overgrowth, but ex, mer double mutants cause a much stronger overgrowth phenotype, similar to hpo or wts mutants (Hamaratoglu et al, 2006).

Of course, evolutionists since the modern synthesis have known that the source of heritable variation in structures like eyes is mutation of the genes involved in "making" those eyes.

The researchers took female fruit flies from six different strains and mated each with two males: one guy, with an eye-color mutation, got lucky every time; the other was a male picked from one of the six strains.

Similar to the lens in the eye, where mutations in Cx46 and Cx50 cause cataracts [11], [17], the sensory epithelium in the cochlea is an avascular organ.
