What is the phenotype of the genotype RrYy?

Can you determine a phenotype from a genotype?

The term “phenotype” refers to the observable physical properties of an organism; these include the organism’s appearance, development, and behavior. An organism’s phenotype is determined by its genotype, which is the set of genes the organism carries, as well as by environmental influences upon these genes.

When RrYy and RrYy are crossed in f2 generation the ratio of RrYy will be?

2 : 1 : 4 : 2.

What are the expected phenotype in f2 generation of the cross RrYy and RrYy?

Only wrinkled seeds with yellow cotyledons.

How do you find the phenotypic ratio?

Write the amount of homozygous dominant (AA) and heterozygous (Aa) squares as one phenotypic group. Count the amount of homozygous recessive (aa) squares as another group. Write the result as a ratio of the two groups. A count of 3 from one group and 1 from the other would give a ratio of 3:1.

What are the expected phenotypic and genotypic ratios from a cross of two f1 individuals?

Tutorial. The expected genotype ratio when two heterozygotes are crossed is 1 (homozygous dominant) : 2 (heterozygous) : 1 (homozygous recessive). When a phenotypic ratio of 2 : 1 is observed, there is probably a lethal allele.
