(ii). Determine which color is dominant.
(iii). Work out the ratio of brown to white in the ‘grandchildren.’

(i). Determine the color of Bob. BOB IS WHITE
(ii). Determine which color is dominant. BROWN IS DOMINANT
(iii). Work out the ratio of brown to white in the ‘grandchildren.’
PHENOTYPIC RATIO BROWN TO WHITE 3:1
(iv). If the researcher crosses two of the white 'grandchildren', determine the color of their offspring. THE WHOLE PROGENY WILL BE WHITE
