What else can I help you with?
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 Punnett square would show that all offspring would be heterozygous for the trait, meaning they would have one allele for tall plants and one allele for short plants. This would result in all offspring being tall plants phenotypically, but carrying the allele for short plants.
How do you use a Punnett Square and what do they do?
A Punnett Square is a tool used to predict the ratio of genotypes and phenotypes in offspring based on the genetic traits of the parents. It helps to illustrate the possible combinations of genes that can result from a genetic cross between two individuals. By filling in the squares with the parents' alleles, you can determine the probability of different outcomes in the offspring.
What are the genotype a of the parents?
genotype of the parents - parents will be heterozygous dominant. e.g. take the example of Mendel's pea cross. if parent is heterozygous dominant then the genotype will be Tt and Tt now if you will do a cross then the result you will get is this - Tt X Tt result - TT, Tt, Tt, tt it gives a 3 : 1 ratio i.e. three tall and one dwarf.

What is a chart that shows all the possible combinations of alleles that can result from a genetic cross called?
A Punnett square is a chart that shows all the possible combinations of alleles that can result from a genetic cross. It allows for predicting the probability of certain traits in offspring based on the genotypes of the parents.
What is the probable genotype for the two parents of a cross between two pea plants?
Crossing between two parents is done to combine noble characters of parents into the next generation. Suppose a dwarf pea plant has better quality of pods and its tall counterpart has more number of pods per plant then a plant breeder may think of combining these two characters into its hybrid. The genotype for these tall & dwarf parents with variable pod quality and quantity may be designated as - Tall parent --- ppTT & dwarf parent -- PPtt
Why does the cross between two parents that are homozygous for contrasting traits result in offspring that are heterozygous?
They R pretty wierd!
Is a chart used to show the possible outcomes of allele combinations that parents can pass on to their offspring.?
Punnett Square
How do you make a pun nett square to show how many offspring will be heterozygous?
First, draw a box, then divide it in four. Let's say we're testing for the genotypes of the offspring of parents with TT and Tt genotypes. Above the first box, write one allele of a parent, or in this case, T. Above the box to the right of it, write another T for the parents' other allele. Do the same down the left side of the four boxes with the other parent's genes. Now, this is a bit like finding coordinates. In the first box, write the allele of the gene above it, and to its left. That is one possible genotype of the offspring. Repeat this for all squares. In our case with the parents being TT and Tt, the four offspring in the Punnett squares will have only two possible genotypes; TT or Tt, like their parents. This will show you how many chances the offspring have of being heterozygous, homozygous dominant, or recessive.

Show the cross between 2 heterozygous dogs. black fur B is dominant to brown fur b?
The Punnett square for crossing two heterozygous dogs (Bb x Bb) would result in a 25% chance of offspring with homozygous dominant black fur (BB), a 50% chance of offspring with heterozygous black fur (Bb), and a 25% chance of offspring with homozygous recessive brown fur (bb).
What can you predict about the offspring if you know the genotypes of the parents?
So, if one parent is Aa (heterozygous) and the other parent is aa (homozygous recessive) the punnett square would look like this: ___|_A__|__a_ _a_|_Aa_|_aa_ _a_|_Aa_|_aa_ The genotypes of the offspring 50% heterozygous and 50% homozygous recessive

What cross between parents will result in an approximate 3 to 1 ratio?
A monohybrid cross is a cross between parents who are heterozygous at one locus; ... The results The wrinkled trait --- which had disappeared in his hybrid ...of them produced both types of seeds in the F3 and - once again - in a 3:1 ratio
What is the probability that two heterozygous parents would have an offspring that produced round seeds from Mendel?
When both parents are heterozygous for seed shape (Rr, where R is the allele for round seeds and r is the allele for wrinkled seeds), the probability of producing an offspring with round seeds can be determined using a Punnett square. The possible genotypes are RR, Rr, Rr, and rr. Thus, there are three combinations (RR and Rr) that result in round seeds out of four total combinations. Therefore, the probability of having an offspring with round seeds is 3 out of 4, or 75%.
What do punnett squares predict?
Punnett squares predict the possible genetic outcomes of a cross between two individuals, including the likelihood of different traits being passed on to offspring. They show the potential combinations of alleles that can result from the genetic contributions of each parent.
What are the genotype a of the parents?
