1998-1999 project with Christian White and Quency Thomas

Body color: wild-type on the left and ebony on the right

Eye color: wild-type and white

1999-2000 project with Eric Scott

Eyes absent (eya) lacks the compound eyes and the optic lobes of the brain for which the eye has a positive trophic influence (although the 3 simple eyes (ocelli) remain)

Here are two higher magnification pictures (first and second) showing that there is eye color pigment in the ocelli, demonstrating that my eyeless stock is wild-type (red-eyed) for eye color

picture of F2 of w female x eya male. Top left red eyed females and males. Top right white eyed males and females. bottom left eya females and males. Bottom right enlargement of eya females.

picture showing that eya females in F2 can be either red eyed or white eyed

picture of F2 of eya female x white male. Top left - there are red and white eyed males. Top right - all females are red eyed. Bottom left - there are eya females and males. Bottom right enlargement of eya female.

picture showint that ocelli can be white or red eyed in males

picture of a typical female all of which had red ocelli

2000-2001 project with Dinko Vujic and Scott Dintleman

Parental (P1) flies:

picture Glass (gl) shows abnormal compound eye in male (top left) and female (top right) with "pink dot" phenotype. Compound eye is small and disorganized (bottom left) and so are ocelli (3 simple eyes, bottom right)

picture White eyed "none" (no ocelli narrow eyes) shows abnormal compound eye in male (top left) and female (top right) with white-eyed phenotype. Compound eye is small and disorganized (bottom left) and so are ocelli (3 simple eyes, bottom right)

picture White eyed flies show normal compound eyes in male (top left) and female (top right) with white-eyed phenotype. Compound eye is normal (bottom left) and so are ocelli (3 simple eyes, bottom right)

Filial (F1 and F2) generations

picture Wild-type flies shows normal compound eye with black dot (pseudopupil) in male (top left) and female (top right) with red eyed phenotype. Compound eye is normal and shows a bright pseudopupil (bottom left) and ocelli are also (3 simple eyes, bottom right)

picture A red eyed "none" (no ocelli narrow eyes) phenotype shows up in F1, suggesting that none and glass are alleles of the same gene and that none is dominant to glass. Abnormal compound eye in male (top left) and female (top right) with red eyed phenotype. Compound eye is small and disorganized (bottom left) and so are ocelli (3 simple eyes, bottom right)

picture White eyed glass (gl) shows up with abnormal compound eye in male (top left) and female (top right) but without "pink dot" phenotype. Compound eye is small and disorganized (bottom left) and so are ocelli (3 simple eyes, bottom right)
