Gene cross bio question

answer is C
i though D could be the answer as it will only produce dominant phenotypes and heterozygous for all so gives 1;1;1;1 ratio


BbSs x BbSs gives a ratio 1:1:1:1 of phenotypes BS : Bs : bS : bs

bbSS x BBss gives a ratio 16:0 = 1:0 of phenotyes BS and nothing else

ohhhh i see my mistake
