WebWhen Calvin Bridges observed a large number of off-spring from a cross of white-eyed female Drosophila to red-eyed males, he observed very rare white-eyed females and red-eyed males among the offspring. He was able to show that these exceptions resulted from nondisjunction, such that the white-eyed females had received two Xs from the egg … WebExplain how Bridges's study of nondisjunction in Drosophila helped prove the chromosome theory of inheritance. Bridges showed that in crosses with white-eyed flies, a sex-linked trait, exceptional progeny had abnormal inheritance of sex chromosomes.

WebNondisjunction of X chromosomes results in eggs containing either two X chromosomes or no X chromosome. The exceptional white-eyed females would contain two X chromosomes plus a Y chromosome (genotype w-/w-/Y), and the exceptional red-eyed males would contain a single X chromosome and no Y chromosome (genotype w+). WebCalvin Bridges determined that the rare white‑eyed males produced from the mating of true‑breeding red‑eyed females with white‑eyed males resulted from a nondisjunction of X chromosomes in the female parent during meiosis.
