I'm confused about phenotype and genotype ratio after you do a monohybrid cross.
for example, after the cross, I have RR Rr Rr rr, the genotype is 1:2:1 and the phenotype is 3:1, right?
but what if I have Rr Rr rr rr? Is the phenotype 2:2 and genotype 1:1?
what about Rr Rr Rr Rr?
My book doens't explain it very well, please help me guys!
hey i so don't get it either
does anyone know how to use phenotype ratios its so confusing i am just trying to raise my grade being in high school its rough i really need to good i don't feel like retaking classes as a junior or sophomore so i really need help in school it is like learning a new language so if anyone can help me i will soooooo appreciate it

I have a 7 page homework assignment that I'm deffintly not going to finish..Here's an example of a question... In mice, long ears is dominant to short ears. What are the genotypic and phenotypic ratios id you cross a homozygous long eared mouse with a short eared mouse? so yeah..can anyone help me?! pleaaaase... if so like send me a pm or something and I'll hopefully get this done!
