Take this cross for example: GG x GG
I know the genotypic and phenotypic ratios will both be 100%, but I'm confused on how the ratios are supposed to be written. When there's a cross between two heterozygous, the genotypic ratio is 1:2:1 where the first number is homozygous dominant, second is heterozygous, and third is homozygous recessive. But how would you write it if one or more values are missing? In my example, there are no second and third values. Would you just write 1 as the ratio, or 1:0:0?
