genotype means genetic make up. it can give the information about the parents wether they were homozygous or heterzygous

Answer (Improved)A genotypic ratio is the proportion of genotypes found in individuals after a cross. For example, consider a cross between two heterozygous individuals for trait A:

Aa X Aa

The result is a 1:2:1 ratio for the genotypes AA, Aa, and AA respectively. Put another way, if the parents had 100 offspring, 25 would be expected to have the genotype AA, 50 the genotype Aa and 25 the genotype AA.

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).


A grasshopper with red stripes mates with a grasshopper with yellow stripes What ratio would you expect to see in the phenotypes of their offspring?

You would expect to see a 1:1 ratio of offspring with red stripes to offspring with yellow stripes. This is because the offspring would inherit one allele for red stripes and one allele for yellow stripes, resulting in a 1:1 genotypic ratio.


What would be the offspring be if a roan cow and a white bull were bred together?

The offspring produced is dependent on chances. We can figure out the chances of the kind of offspring such a cross will get by using a Punnett square. Unfortunately the WYSIWYG format on this site will not allow for such a square, so we will give the ratio, the genotypic and phenotypic percentages that such a cross will receive. Let R = red, W = white and RW = roan. Roan cow (RW) x White bull (WW) Offspring: 2 RW : 2 WW Genotypic ratio: 50% roan and 50% white Phenotypic ratio: Same as above. Thus, the offspring of a roan cow crossed with a white bull (presumably of the same breed, being Shorthorn), may come out as white or roan. There is a 50% chance that either will occur.


A blue feathered bird is crossed with a white feathered bird All the F1 generation are blue What would be the genotype for the F2 generation?

The F2 generation would have a mix of genotypes for feather color, depending on the genetic makeup of the F1 birds. Assuming the blue feathered bird is homozygous dominant (BB) and the white feathered bird is homozygous recessive (bb), the F1 generation would be heterozygous (Bb). In the F2 generation, there would be a phenotypic ratio of 3:1 for blue to white feathers and a genotypic ratio of 1:2:1 for BB:Bb:bb.


What is the relation between internal and external reflux ratio in distillation column?

The internal reflux ratio is the ratio of the liquid returned as reflux to the distillate product inside the column, while the external reflux ratio is the ratio of the liquid refluxed back to the column to the distillate product taken out of the column. These ratios are related as the sum of the internal and external reflux ratios is equal to the total reflux ratio, which can affect the separation efficiency and energy consumption in a distillation column.

What a ratio?

A genotypic -ratio reflects the genetic configuration of an individual in the population. Several genotypes are possible in a phenotype and the ratio in which the genotypes segregate in a given phenotype is known as its genotypic ratio.


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

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

To determine the genotypic ratio in a genetic cross, you can use Punnett squares to predict the possible combinations of alleles from the parents. By analyzing the different genotypes that can result from the cross, you can calculate the genotypic ratio by counting the number of each genotype and expressing it as a ratio.


What is the genotypic ratio for this cross?

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.


What is the genotypic ratio of the offspring from a cross of AAA x AAA?

The genotypic ratio of a cross of Aa and Aa is: one AA, one aa, and two Aa. Or 1:2:1


What is the genotypic ratio for two parents with the genotypes AAA and AAA?

The genotypic ratio for two parents with the genotypes AAA and AAA is 1:0. This means that all offspring will have the genotype AAA.


What is the expected genotypic ratios for di-hybrid cross and mono-hybrid cross?

In a dihybrid cross, the expected genotypic ratio is 1:2:1 for homozygous dominant: heterozygous: homozygous recessive genotypes, respectively. In a monohybrid cross, the expected genotypic ratio is 1:2:1 for homozygous dominant: heterozygous: homozygous recessive genotypes, respectively.


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 genotypic ratio for these two hybrids one hybrid and one homozygote and two homozygotes?

To determine the genotypic ratio for the crosses involving one hybrid (heterozygous, Aa) and one homozygote (AA or aa), you can set up a Punnett square. For a cross between Aa and AA, the genotypic ratio would be 1 AA : 1 Aa. For a cross between two homozygotes (AA x aa), the ratio of genotypes would be 100% Aa. Thus, the ratios depend on the specific homozygote involved in the cross.


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.


What is the genotypic ratio for a tetrahybrid cross?

1:1:1:1:1:1:1:1 ratio is the expected outcome of a heterozygous (BbGgCc) and a homozygous recessive (bbggcc) cross.
