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.

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
Which choice represents a dihybrid cross?
two sets of genes on nonhomologous chromosomes
What is individuals having two of the same alleles of a gene?
A monohybrid cross is a cross between two individuals that are homozygous for different alleles of the same gene. An example is a cross between a red-eyed (RR) fruit fly and a white-eyed (WW) fruitfly.
An individual with the genotype AaBb produces four different gametes in equal proportions This is a demonstration of?
law of independent assortment b
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
A cross between organisms with the genotypes AaBb and AaBb called?
This is called a dihybrid cross in which both parents are heterogeneous.
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)
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 color is a person with AAbb genotype?
if a man were non- hemophiliac and he marries a woman whois homozygus for nan-hemophilia,give the possible genotypes of the children
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 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.
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
Which choice represents a dihybrid cross?
two sets of genes on nonhomologous chromosomes
