Ab and ab
There would be about a 50/50 ratio of each.
The percentage of AB gametes produced by an AaBb parent is 25%. This is because during meiosis, the two alleles segregate independently, resulting in equal proportions of gametes with different combinations of alleles (AB, Ab, aB, ab). By calculating the possible combinations, we see that only 25% will be AB gametes.
Each time a gamete is formed, one allele from each gene (i.e. either A or a) is included.This means for an individual with AaBbCc, there are 8 different gametes:ABCABcAbCAbcaBCabCaBcabc

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.
This is a demonstration of independent assortment, which is a principle of Mendelian genetics stating that genes assort independently of each other during gamete formation. In this case, the alleles for traits A and B are sorting independently of each other, resulting in the production of four different gametes in equal proportions.

In the F2 generation, the possible gametes produced would be the result of the random assortment of alleles from the parents. Each parent can produce two types of gametes based on their genotype. For example, if the parents are AaBb and AaBb, the possible gametes would be AB, Ab, aB, and ab.
You need to make a Punnet Square Put A and a on top and B and B on the left side. These represent the possible gametes. Your results should be: AB AB Ba (aB) Ba (aB) So 50% of the genotype have the A allele.
The percentage of AB gametes produced by an AaBb parent is 25%. This is because during meiosis, the two alleles segregate independently, resulting in equal proportions of gametes with different combinations of alleles (AB, Ab, aB, ab).

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)
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.
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.
This is a demonstration of independent assortment, which is a principle of Mendelian genetics stating that genes assort independently of each other during gamete formation. In this case, the alleles for traits A and B are sorting independently of each other, resulting in the production of four different gametes in equal proportions.
A gamete is haploid (1N) so 'Aa' & 'AA' are diploid and during cell division (mitosis) gametes are formed and then 2 gametes merge together to make a diploid (think of sperm and egg, each is haploid or 1N, when fertilization occurs the egg and sperm form 1 cell that is 2N or diploid). So the possible gametes for 'Aa' would be 'A' & 'a' while for 'AA' the only gametes possible are 'A' If the question is asking what the possible gametes are for 'AaBB' the haploid (gamete) can be 'AB' or 'aB'
