The genotype against the immediate environment and developmental processes. Each organism has a unique environment too. Think about it. Even identical twins are not totally their genotype because they are subject to not only the same environment, usually, but the unique experiences and formative processes of their unique environment.

What is the probability that any of the offspring between individuals with the genotype AABbCcddEE will have the genotype AABBCCddEE
The phenotypes for the genotype "yellow body color is dominant to blue" would be yellow body color for individuals with at least one dominant allele for yellow (Y allele) and blue body color for individuals with two recessive alleles for blue (yy genotype).
The parents can pass on only the alleles of their genotypes to their offspring. Therefore, the offspring genotypes and phenotypes are dependent solely upon the alleles inherited from the parents.
To perform a testcross, you cross an individual with a dominant phenotype (but unknown genotype) with a homozygous recessive individual. By examining the offspring's phenotypes, you can determine the genotype of the unknown individual through the principles of Mendelian genetics. This allows you to determine if the individual is homozygous dominant or heterozygous for a specific trait.
To determine the genotype of an individual who is heterozygous for a trait, you would need to perform a genetic cross with a homozygous recessive individual. By observing the phenotypes of the offspring, you can deduce the genotype of the heterozygous individual. This can help determine if the heterozygous individual is carrying one dominant and one recessive allele.
Phenotypes are the traits expressed by the genotype. So, for blood type, a person can have A and i alleles (genotype). However, in the phenotype, since i is recessive, only the A will be expressed, and the person will have an A blood type.
If the parents both have the genotype Aa, their children could have the genotypes AA, Aa, or aa. The possible phenotypes for their children would be individuals with type A blood (AA or Aa genotype) or type O blood (aa genotype).
Perform a test cross. Cross the organism with an organism with a homozygous recessive genotype and use the phenotypes of the offspring and a Punnett square to figure out the unknown genotype.
The genotype is homozygous recessive or the recessive trait is on the X chromosome and has no corresponding allele on the Y chromosome.
Phenotypes are the traits expressed by the genotype. So, for blood type, a person can have A and i alleles (genotype). However, in the phenotype, since i is recessive, only the A will be expressed, and the person will have an A blood type.
To effectively write genotype and phenotype ratios in a genetic study, one must first determine the possible genotypes and phenotypes based on the traits being studied. Then, the ratios can be expressed by listing the different genotypes and phenotypes and their frequencies in the population being studied. This helps to show the inheritance patterns and relationships between different traits.
