Can you show the Punnett square results of a cross between two heterozygous parents?

the possible combination for the F2 are: by example if we have the gene T dominant and t recessive from the father and the same gene Tt from the mother . the gene possible will be TT,Tt,Tt and tt.

What goes on the outside of a Punnett Square?
On the outside of the Punnett Square you put the genotype or two alleles of the parents.
If the allele for yellow peas is dominant to the allele for green peas what experiment do you do to find out if the yellow peas are homozygous dominant or heterozygous?
You will need to place the genetic combination possibilities into at least two Punnett Squares where Y=dominant yellow and g=recessive green symbols are assigned . Observe the outcome of the crosses which should reflect a specific probablity of results shown as follows: YY X gg yields 100% Yg heterozygous combinations with yellow appearance and could be dominant but further experimentation is needed to confirm. Yg X gg yields 50% heterozygous offspring (yellow appearance) with 50% homozygous (green appearance). If other results are observed after these two genetic combinations then yellow is not dominant to green. Lastly comparing the results between the two crosses will help you narrow the distinction between homozygous and heterozygous characteristics. Research: Punnett Squares further if you are not familiar with its dynamics. Good luck!
In a Punnett square a capital letter stands for a allele.?
Capital letters on Punnett Squares represent dominant genes, while lowercase letters represent recessive genes. For example, if the trait "T" is a tall gene and the trait "t" is a short gene. When you get your results (if both parents are heterozygous for tallness, Tt) you get four possible results, 1 TT (homozygous tall), 2 Tt (twice, heterozygous tall Tt), and 1 tt (homozygous short). If there is a dominant gene there, that gene will be displayed. Only if there are two recessive genes will the recessive trait be displayed.
How will you calculate the phenotype ratio of a cross between dihybrid F1 plants that are heterozygous for 2 dominant traits?
Using a Punnett square, you can calculate the genotype and phenotype of two dihybrid plants. For example, if you have two heterozygous individuals for two dominant traits (we'll pretend the genotype is YyRr), put them into a Punnett square, and you'll get these results: YYRR: 1, YYRr: 2, YYrr: 1 YyRR: 2, YyRr: 4, Yyrr: 2 yyRR: 1, yyRr: 2, yyrr: 1 Phenotypes expressed: Dominant for both traits: 9/16 Dominant for trait 1: 3/16 Dominant for trait 2: 3/16 Recessive for both traits: 1/16 Therefore, the ratio would be 9:3:3:1

Are punnett squares used to show the results of sexual or asexual reproduction?
Sexually because of the genetic variation between parents. Asexuals can't really use punnett squares because only one parent is there and no variation really occurs except through mutations.

How do you use a Punnett Square and what do they do?
A punnett square shows the possible outcomes of a certain trait based on the parents genes. To use the Punnett square, you put pairs of genes in the diagram and then determine the crosses that will come from those combinations. It is useful when dealing with hybrid and dihybrid crosses to determine the genotypic and phenotypic ratios.
What is the square used to determine probabillity and results of cross is called?
Square used to determine probability and results of cross is called a Punnett square. It is named after Reginald C. Punnett.
