Fossils are physical evidence of preexisting organisms, either plant or animal. ...

Cells divide for many reasons. For example, when you skin your knee, cells divide to replace old, dead, or damaged cells. Cells also divide so living things can grow. When organisms grow, it isn't because cells are getting larger.
Answer:
We need to cross a white eyed female (XwXw) and red eyed male (XRY).
The cross can be shown as:
Xw Xw
XR XRXw (female, red eyed) XRXw (female, red eyed)
Y XwY (male, white eyed) XwY (male, white eyed)
Thus, in the offspring we will have the following phenotype:
Males: White eyed.
Females: Red eyed.
