drosophilila fly experiment, need help with the diagram to explain the results of the crosses=XR, =Xr help pse

Question

XR and Xr are the symbols,
the F2 crosses are red males= XR Y
white females = Xr Y
Females homozygote = XR XR
Females hetrozygote = XR Xr

if homozygote cross, XR XR + Xr Y
if hetrozygote cross, XR Xr + Xr Y

PLEASE EXPLAIN DIAGRAMES IF POSSBLE, OR SHOW, WOULD MUCH APPRICIATE THE ASSISTANCE

Answer 1

female homozygous cross:

.......XR....XR
Xr XRXr XRXr
Y XRY XRY

that would be 50% probability of red females (XRXR) and 50% of red males (XRY).


for the heterozygous cross:

.......XR....Xr
Xr XRXr XrXr
Y XRY XrY

that would be 25% possibility of red females (XRXR), 25% of white female (XrXr), 25% white male (XrY), 25% red male (XRY).
