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?
The phenotypic ratio of the cross AaBb x AaBb is 9:3:3:1, which represents the different possible combinations of genotypes for the offspring based on the principles of Mendelian genetics. This ratio indicates that 9 out of 16 offspring will exhibit the dominant phenotype for both traits, while 3 out of 16 will exhibit one dominant and one recessive phenotype, 3 out of 16 will exhibit the other dominant and recessive phenotype, and 1 out of 16 will exhibit both recessive phenotypes.

Which cross will yield four phenotypes in the 1111 ratio?
For example:Scented (S) is dominant, odorless (s) is recessive, Smooth (O) is dominant, hairy (o) is recessive.a heterozygous scented, smooth-stemmed plant (SsOo) crossed with a fully homozygous odorless, hairy-stemmed plant (ssoo) will get offspring with phenotype ratio 1:1:1:1.Offspring:SsOo (scented, smooth), ssOo (odorless, smooth), Ssoo (scented, hairy), ssoo (odorless, hairy) = 1:1:1:1.
How many different phenotypes can be produced from intercrossing parents of genotype AaB1B2?
Four different phenotypes can be produced: AABB, AABb, AaBB, and AaBb. This is the result of different combinations of alleles from each parent in the offspring.
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
What is the phenotypic ratio of the following dihybrid cross AaBb x AaBb?
The phenotypic ratio of the cross AaBb x AaBb is 9:3:3:1, which represents the different possible combinations of genotypes for the offspring based on the principles of Mendelian genetics. This ratio indicates that 9 out of 16 offspring will exhibit the dominant phenotype for both traits, while 3 out of 16 will exhibit one dominant and one recessive phenotype, 3 out of 16 will exhibit the other dominant and recessive phenotype, and 1 out of 16 will exhibit both recessive phenotypes.
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)

Which cross will yield four phenotypes in the ratio?
A phenotype is the composite of an organism's observable traits. The answer to the question, the cross that will yield four phenotypes in the 1:1:1:1 ratio is fifty.
A cross between organisms with the genotypes AaBb and AaBb called?
The offspring of a cross between organisms with the genotypes AaBb and AaBb would be referred to as a dihybrid cross, focusing on two different gene pairs (A/a and B/b) segregating independently. The resulting offspring would have a genotype ratio of 9:3:3:1 in a typical Mendelian inheritance pattern.
When was AABB created?
AABB was created in 1947.
How many different phenotypes can be produced from intercrossing parents of genotype AaB1B2?
Four different phenotypes can be produced: AABB, AABb, AaBB, and AaBb. This is the result of different combinations of alleles from each parent in the offspring.
