What is a tool for predicting genotypes of offspring?
In genetics a type of grid is used to show the gametes of each parent and their possible offspring and also called the checkerboard is used. The Punnet Square is named after Reginald Crundall Punnett an English geneticist.
How do you get the genotype of the phenotype?
In order to determine the phenotype of the original organism observe any physical traits / characteristics Lookup the following concepts: punnet square, homozygous recessive/dominant. Draw the punnet square Determine the crossing Determine the dominant traits Determine the phenotype
If you made a Punnett square showing Gregor Mendels cross between true breeding short plsntd the square would show that the offspring had what?
the genotype of one of the parents
What can a punnett square tell us?
Punnett squares demonstrate the percentage of traits that are passed on from one generation to the next. It shows the pairings of dominant and recessive genes and what percentage there is of the next generation having those particular traits.
How do you make a punnett square in sex limited?
It would be exactly the same way you make any punnet square. Just remember that the Y chromosome on males is recessive to the X chromosome. So for example, if a certain recessive phenotype is carried on the X chromosome, and the offspring is a male, the male will show that phenotype (because Y is recessive to X). However if it is a female, she will not show the phenotype because we said it is a recessive X linked phenotype.

Compare and contrast genotype and phenotype?
An organism's genotype is its genetic identity. The genotype is comprised of all the genetic material inherited from both parents. The genotype is what "tells" each individual cell how to function. The phenotype is the physical expression of an organism's genotype. For example, if a person's genotype for eye color is one dominant allele for brown and one recessive for blue, then the individual's phenotype would be their actual eye color which in this case would be brown.

Does a punnet square show the genotype?
no
What does the punnett square show of a carrier girl and a colorblind boy?
you have to determine what traits are used before you can do it and look at punnett square
Does a Tt plant have the same genotype as a TT plant?
Nope! TT is the dominant phenotype (what ever it may be) and tt is the recessive phenotype (what ever that may be).So say T is the allele for Tall plants, t is the allele for short plants. TT would be show the tall phenotype while tt would show the short phenotype. If the genotype was Tt, the phenotype would be tall as well because the T is dominant and masks the phenotype of t (short plants).
Can 2 organisms have different genotypes but the same phenotype?
No. It is possible for the reverse to be true, two organisms can have the same phenotype but a different genotype. This is because the phenotype is what you will see on the outside whereas the genotype is the combination of alleles and since this determines the phenotype, two organisms with the same genotype will have the same phenotype. So, basically, no. Actually 2 organisms can certainly have different phenotypes with the same genotype--this refers to the concept of penetrance. Some people can have the gene for a condition but never show symptoms. An excellent example of this is the disease neurofibromatosis. This disease has very variable penetrance in which a child of an affected parent may show no signs of the disease, but then have a child with a severe form.
What is an individual with genotype AAA described as?
An Aa genotype can result in the same phenotype as either an AA or AA genotype, if one of the alleles acts in a dominant fashion. If the A allele is dominant over the a allele, then the phenotype of a heterozygous (Aa) individual will be the same as the phenotype of a homozygous dominant (AA) individual.
How does a punnett square show precetages of phenotypes and geneotypes?
Punnett Squares do not directly tell you the percentages of phenotypes and genotypes, it tells you the probability of the expected genotypes. Based on the Punnett Square, you can infer about the genotypic and phenotypic ratios.
