i dont get it i have to redo

So you have to flip a coin for this, heads= dominant, which is R= red and tails will equal recessive: which is r. And you need to flip the coin twice so you can get 2 alleles, and once you get the genotype, you can determine the phenotype, which is how each off spring will look, if you get RR for genotype when flipping the coin twice, the fur colour will be red, because R= red and there are 2 of them so it will be dominant, if you get Rr, then the fur colour will be red again because R is dominant and if you get rr, then the fur colour will be blue, because there are only recessive alleles and no dominant ones. Just do the same thing for the rest of these.

Hope that helps!
