A ratio of phenotypes produced by a cross is a description of the expected proportion of different physical traits or characteristics that offspring will inherit from their parents. This ratio is determined by the combination of genes passed down from each parent, and can be predicted using Punnett squares or other genetic tools.
A phenotype is the composite of an organism's observable traits. The answer to the question, the cross that will yield four phenotypes in the 1:1:1:1 ratio is fifty.
3:1 ratio of dominant to recessive phenotypes.
The phenotypic ratio resulting from a dihybrid cross showing independent assortment is expected to be 9:3:3:1. This ratio is obtained when two heterozygous individuals are crossed for two traits that are independently inherited. The ratio represents the different combinations of phenotypes that can arise from the cross.
The result of crossing two individuals who are heterozygous for two different traits (LlGg x LlGg) would typically follow a 9:3:3:1 phenotypic ratio for a dihybrid cross. This means you would expect to see a mix of four different phenotypes in the offspring, with a 9:3:3:1 ratio between those phenotypes.
The phenotypes for the above cross would be 3 individuals with straight hair and 1 individual with curly hair.

The genotypic ratio for a cross refers to the ratio of different genetic combinations that can result from the mating of two individuals. It is typically represented in terms of the different possible genotypes that can be produced.
All you need to do is use a Punnet Square for this. You will get the following genotypical and phenotyical ratio from this cross: RrBb x RRbb = RRBb RrBb RRbb Rrbb In terms of phenotypical ratios, 50% of the offspring have a chance of showing R and B, and the other half have the chance of showing R and b.

This means you would expect to see a mix of four different phenotypes in the offspring, with a 9:3:3:1 ratio between those phenotypes.
The expected phenotype ratio of seed color in the offspring of an F1 x F1 cross is 3:1. This is because the F1 generation is heterozygous for the trait, resulting in a 3:1 ratio of dominant to recessive phenotypes in the offspring.
The phenotypes for the above cross would be 3 individuals with straight hair and 1 individual with curly hair.

For example:Scented (S) is dominant, odorless (s) is recessive, Smooth (O) is dominant, hairy (o) is recessive.a heterozygous scented, smooth-stemmed plant (SsOo) crossed with a fully homozygous odorless, hairy-stemmed plant (ssoo) will get offspring with phenotype ratio 1:1:1:1.Offspring:SsOo (scented, smooth), ssOo (odorless, smooth), Ssoo (scented, hairy), ssoo (odorless, hairy) = 1:1:1:1.
