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.

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 1 to 2 to 1 phenotypic ratio in the F2 generation of a monohybrid cross is a sign o?

A 1 to 2 to 1 phenotypic ratio in the F2 generation of a monohybrid cross is a sign of incomplete dominance, where the heterozygous genotype results in an intermediate phenotype. This ratio is typical when one allele is not completely dominant over the other, leading to a blended or mixed phenotype in heterozygous individuals.


What is a phenotypic ratio?

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.


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.

The phenotypic ratio resulting from a dihybrid cross showing independent assortment is expected to be what?

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.

Why does the expected genotypic ratio often differ from the expected phenotypic ratio from monohybrid cross?

Because in heterozygotes, both alleles are transcribed and translated.


What is the phenotypic ratio of the?

Asuming that the F1 generation is heterozygous for a single trait and that the F2 cross is of 2 F1 offspring. Ex. Aa X Aa the phenotypic ratio is 3:1 dominant to recessive. The genotypic ratio is 1:2:1 AA:Aa:aa.


What is a monohybrid ratio?

A monohybrid ratio refers to the genotypic and phenotypic ratio seen in the offspring of a genetic cross involving only one trait. For example, in a monohybrid cross between two heterozygous individuals (Aa x Aa), the genotypic ratio among the offspring would be 1:2:1 for AA:Aa:aa, and the phenotypic ratio would be 3:1 for the dominant trait to the recessive trait.

How ratio of dihybrid cross can modify?

The ratio of a dihybrid cross can be modified by factors such as gene linkage, epistasis, and incomplete dominance. In a typical dihybrid cross involving two independently assorting traits, the expected phenotypic ratio is 9:3:3:1. However, if the genes are linked (located close together on the same chromosome), the ratio may deviate from this expectation. Additionally, epistatic interactions can alter the phenotypic outcomes, leading to different ratios depending on how the genes interact.


What is the phenotypic of the F2 generation?

This ratio is typical when one allele is not completely dominant over the other, leading to a blended or mixed phenotype in heterozygous individuals.


What kind of phenotype ratio would you expect from a mono-hybrid cross?

possible mendelian ratios for monohybrid cross genotype is 1:2:1 and phenotype is 3:1


In aquirrelsblack fur is recessive to grar fur show the genotypic and phenotypic ratios of a cross between a heterozygous gray squirrel with a black squirrel?

The genotypic ratio would be 1:2:1 (1 BB, 2 Bb, 1 bb) and the phenotypic ratio would be 3:1 (3 gray squirrels : 1 black squirrel).
