A ratio that shows the different outcomes you can get from a genetic cross.

A ratio that shows the varied outcomes that results from a genetic cross and is based on physical appearance alone. For example yellow flowers, round seeds, brown hair, green eyes etc.

The genetic make up of an organism is called genotype and the external appearance or expression of the genetic make up is called phenotype (Color, height, shape etc.). The ratio indicates the number of heterozygotes and homozygotes with reference to the genotypic ratio and to the number of phenotypes expressed as phenotypic ratio. The concept was given by Sir Gregor Johann Mendel, Father of Genetics who worked on pea plant with reference to 7 different characters. The result obtained for a cross between a single character is called monohybrid cross and the ratio is referred to as monohybrid ratio which is 1:2:1 for genotypic ratio and 3:1 for phenotypic ratio.

in the dihybrid cross for the phenotypic ratio it is 9:3:3:1.

What will be the phenotype ratio of the offspring?

9:3:3:1 is the phenotypic ratio of the offspring.


If both parents were Dd then what would the phenotypic ratio be?

If both parents were Dd, they would both be heterozygous for a particular trait. The phenotypic ratio of their offspring would likely be 1 dominant : 2 heterozygous : 1 recessive. This is because the dominant allele masks the recessive allele, resulting in a 3:1 ratio.


How can one determine the phenotypic ratio in a genetic cross?

To determine the phenotypic ratio in a genetic cross, you can use Punnett squares to predict the possible outcomes based on the genotypes of the parents. By analyzing the combinations of alleles passed down from each parent, you can calculate the ratio of different observable traits or characteristics in the offspring.


What is the phenotype ratio of a cross between a heterozygous male and female?

The phenotype ratio will depend on the specific genetic traits being studied. In general, a cross between two heterozygous individuals is expected to result in a 3:1 phenotypic ratio, with three-quarters of the offspring displaying the dominant phenotype and one-quarter displaying the recessive phenotype.


A 9331 phenotypic ratio is characteristic of what?

A 9:3:3:1 phenotypic ratio is characteristic of a dihybrid cross where two genes are segregating independently and assorting according to Mendel's law of independent assortment. This ratio is expected when the genes are located on different chromosomes or are far apart on the same chromosome.

What is the phenotypic ratio for 121?

To determine the phenotypic ratio for a specific number like 121, more context is needed regarding the genetic cross or traits being studied. Typically, phenotypic ratios arise from specific genetic crosses, such as Mendelian inheritance patterns (e.g., a 3:1 ratio for a monohybrid cross). If you provide details about the traits and parental genotypes involved, I can help calculate the phenotypic ratio.

What is the phenotypic ratio of the offspring when a tall man marries a short woman?

The phenotypic ratio of the offspring when a tall man marries a short woman is 3:1 (tall/short). The phenotypic ratio is figured by using the punnet square with the dominant allele for tall and the recessive allele for the short gene.

What is the actual ratio of the phenotypic characteristics red 93 white 36?

The ratio of red to white phenotypic characteristics is approximately 93:36, which simplifies to 31:12 when divided by their greatest common factor of 3.

What is ratio for PHenotypic ration TT Tt TT Tt?

The phenotypic ratio for the given genotypes (TT, Tt, TT, Tt) can be determined by identifying the traits represented by these genotypes. In this case, both TT and Tt result in the dominant phenotype, while there are no recessive phenotypes present. Thus, the phenotypic ratio is 4:0, indicating that all offspring display the dominant trait.
