S Smooth texture s shrunken texture The purpose of our lab was to examine the traits exhibited on the kernels of corn found on five different rows and discern the genotypes of the parents of the ear.

. Chi Square Test Expected Number Observed Number expected Purple smooth Total x 916 Purple shrunken Total x 316 Yellow smooth Total x 316 Yellow shrunken Total x 116 CHI SQUARE VALUE add the numbers from the rows above 9. After students collect data on the kernels yellowpurple smoothshrunken they use a chi square analysis to determine if the number was close enough to support the hypothesis that the parents were heterozygous for both traits PpSs xPpSs. There are four grain phenotypes in the ear.

Now determine if your chi. If your answer is correct what ratios for each phenotype should be observed. If the chi-square analysis suggests a new hypothesis have the students come.

Take the squared deviation and divide it by the expected. 34- Purple 34- Starchy Smooth What kernel color is dominant in genetic corn. CORN GENETICS CHI SQUARE ANALYSIS Author.

Chance alone or if the data is significantly different you need to use a chi square test. Prange I acceptreject the hypothesis that the data. In this exercise you will examine an ear of corn and determine the type of cross and genes responsible for the coloration and texture of the corn kernels like the one show below.

Vernon Steve SHS-Staff Created Date. Prediction by performing chi-square analysis. The equation used to find the chi square value is shown below.

These phenotypes and numbers are entered in Columns 1 and 2 of the following Table 2. What genetic cross will give you this ratio. Matthew Lucas CORN GENETICS CHI SQUARE ANALYSIS In this exercise you will examine an ear of corn and determine the type of cross and genes responsible for the coloration and texture of the corn kernels like the one shown below.

It might have been PpSs x Ppss or something similar. In this exercise you will examine an ear of corn and determine the type of cross and genes responsible for the coloration and texture of the corn kernels like the one shown below. Another reason is that multiple genes and alleles dictate texture and color.

If the corn was produced by a dihybrid cross the expected numbers for each phenotype should be as follows. Expected Number Observed Number expected Purple smooth Total x 916 Purple shrunken Total x 316 Yellow smooth Total x 316 Yellow shrunken Total x 116 CHI SQUARE VALUE add the numbers from the rows above 4. P purple color p yellow color.

Corn Dihybrid Genetics Answers Keywords. Access Free Corn Dihybrid Genetics Answers PpSs involving two pairs of heterozygous genes resulting in a theoretical expected ratio of 9331. To determine the p-value you would need to use the chi-square chart.

CORN GENETICS CHI SQUARE ANALYSIS KEY Corn Dihybrid Genetics Answers Author. Write down the. Up to 24 cash back You and your tablemate will answer the following questions in your lab notebook.

Worksheet includes additional chi square problems for practice. 08533 is the chi square value. There are four grain phenotypes in the ear.

Record the Possible Genotypes. A large ear of corn has a total of 433 grains including 271 Purple starchy 73 Purple sweet 63 Yellow. An ear of corn has a total of 381 grains including 216 Purple Smooth 79 Purple Shrunken 65 Yellow Smooth and 21 Yellow Shrunken.

CORN GENETICS CHI SQUARE ANALYSIS. Corn Genetics and Statistical Analysis PowerPoint. DO-E D DPE Phenotypes Observed 0 Expected E Purple Smooth 974 Purple Wrinkled 307 Yellow Smooth 382 Yellow Wrinkled 137 Total 1800 Degrees of freedom.

Test your hypothesis using chi square and probability values. With the aforementioned chi square value and a degree of freedom equal to 1 you will see that the calculated value of 085 lies between 046 and 107. What phenotypic results were expected in the F1 Generation.

Then add all the numbers up to find X2. Students would count the kernels smooth wrinkled purple yellow and determine if the ears of corn are the result of a dihybrid cross RrPp x RrPp. Punnett Square for your proposed cross.

The following Chi Square equation yields the Chi Square Number. There are four grain phenotypes in the ear. 5152017 40900 PM Company.

This ear of corn was produced by a dihybrid cross PpSs x PpSs involving two pairs of. 7302015 Chi Square Analysis Answer Key Corn Genetics 55 Looks like a 9331 ratio meaning the parents are HhEe x HhEe Total number of offspring 100 Expected 916 of 100 5625 316 of 100 1875 316 of 100 1876 116 of 100 62505 40 003 09 54 GOOD FIT. Purple and smooth A Purple and Shrunken B Yellow and Smooth C Yellow and Shrunken D.

Your degrees of freedom df is the number. The genotypes of the parents of this corn are. Purple and smooth A Purple and Shrunken B Yellow and Smooth C Yellow and Shrunken D.

Now determine if your chi square value is a good fit with your data. The chi square data might have had a bad fit if the corn was not a dihybrid cross as expected. The activity uses slides with photos of corn and tables to enter data and perform a chi square analysis goodness of fit test.
