What is the phenotype ratio expected from crossing AaBb X AaBb?

∙ 13y ago
The gametes would be AB, Ab, aB, ab which would go both across the top and down the side of the punnett square.
The genotypic ratio is 1:2:1:2:4:2:1:2:1
1AABB: 2AABb: 1 AAbb: 2 AaBB: 4AaBb: 2Aabb: 1aaBB: 2aaBb: 1aabb
The phenotypic ratio is 9:3:3:1
9AB: 3Ab:3aB:1ab phenotypes

∙ 13y ago3/4 show the dominant trait in Aa x Aa
3/4 show the dominant trait in Bb x Bb
(3/4) x (3/4) = 9/16

What are genotype and phenotype ratios for the dihybrid cross AaBB X AaBb?
The genotypes of this cross are:AA - 25%Aa - 50%aa - 25%The phenotypes of this cross are:Dominant trait (A) - 75%Recessive trait (a) - 25%A ratio of dominant to recessive phenotypes - 3:1
What is the phenotypic ratio of the following dihybrid cross AaBb x AaBb?
These are the phenotypic ratios of each outcome: Dominant A and B: 9/16 Dominant A and recessive B: 3/16 Recessive A and dominant B: 3/16 Recessive A and B: 1/16
What is the genotypes of offspring from the following cross AABB x aabb?
You make a box with 4 boxes in it and then you plug in the parents on the top and the side, which is the BBxBb, and match up the alleles (the letters) like coordinates in a graph. BBBBBBBBbBbb
What are all the possible gametes of an individual with the genotype Aabb?
Ab and ab There would be about a 50/50 ratio of each.
Which choice represents a dihybrid cross?
two sets of genes on nonhomologous chromosomes
What is the phenotype ratio for a recessive trait in Mendels F2 generation?
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 are genotype and phenotype ratios for the dihybrid cross AaBB X AaBb?
The genotypes of this cross are:AA - 25%Aa - 50%aa - 25%The phenotypes of this cross are:Dominant trait (A) - 75%Recessive trait (a) - 25%A ratio of dominant to recessive phenotypes - 3:1
What is the phenotype of all four offspring's?
Generally, if the parents are heterozygous and one allele is dominant over the other there are only 2 phenotypes and 3 genotypes. Parents Aa can produce AA, Aa and aa offspring. If the heterozygous individuals have an intermediate phenotype, then three genotypes and 3 phenotypes are possible. If 2 traits are being studied using heterozygous parents AaBb then the possible Genotypes are AABB, AABb, AAbb, AaBB, AaBb, Aabb, aaBb, aaBB, aabb which is nine genotypes. But there are 4 phenotypes. AABB AABb AaBB AaBb are phenotypically the same. aaBb, aaBB are phenotypically the same. Aabb, AAbb are phenotypically the same. aabb
Where did the ratio 9331 come from include what each of these four numbers mean?
The 9/3/3/1 ration is the ratio of phenotypes that are the result of a dihybrid cross. Consider two genes, A and B, that reside on different chromosomes (so that they independently assort). Assume each gene has two alleles. For A, A is dominant and a is recessive, while for the B gene, B is dominant and b is recessive. Now consider a cross between two individuals that are heterozygous for both genes (this is called a dihybrid cross): AaBb X AaBb There are only 4 possible gametes that each individual can produce (in equal proportion): AB Ab aB ab So if we cross the two we get 16 combinations. This will result in 9 possible genotypes: AABB AABb AAbb AaBB AaBb Aabb aaBB aaBb aabb However, there are only 4 possible phenotypes (with proportion in parentheses): Dominant A and B (9/16) (AABB, AABb, AaBB, AaBb) Dominant A, Recessive B (3/16) (AAbb, Aabb) Recessive A, Dominant B (3/16) (aaBB, aaBb) Recessive A, Recessive B (1/16) (aabb)
When was AABB created?
AABB was created in 1947.
What is a heterozygous genotype for a dihybrid?
AaBb usually, but can also be AAbb or aaBB depending on what they ask you is heterozygous. To be heterozygous for one trait, it's AaBb. To have a heterozygous genotype, unless specified, it can be any of the above.
Which describes a humorous verse with an aabb rhyme structure?
AABB
What is the phenotypic ratio of the following dihybrid cross AaBb x AaBb?
These are the phenotypic ratios of each outcome: Dominant A and B: 9/16 Dominant A and recessive B: 3/16 Recessive A and dominant B: 3/16 Recessive A and B: 1/16
What is the genotypes of offspring from the following cross AABB x aabb?

What are all the possible gametes of an individual with the genotype Aabb?
Ab and ab There would be about a 50/50 ratio of each.
A cross between organisms with the genotypes AaBb and AaBb called?
This is called a dihybrid cross in which both parents are heterogeneous.
