Does a punnet square show the actual results of a genetic cross?
A Punnett square is used to determine an idealized outcome. For example, all possible combinations of genotypes of the gametes are represented, as if they had been actually been produced. The proportions of the various resulting genotypes are also idealized. In actual crosses, the numbers will vary from the idealized numbers due to chance.
What did Mendel observe in the F2 offspring that showed him that the alleles for seed shape segregate independently of those for seed color?
mendel observed independent assortment.independent assortment-genes that segregrate independently.independent assortment. genes assorting randomly.
When is the only time a recessive phenotype can be observed?
A recessive phenotype can only be observed when the individual carries both the recessive alleles for the specific trait.
What kind of specimen can be observed under interference microscope?
specimen observed
What did Mendel call the observed trait and the trait that seemed to disappear?
he called the observed traits dominant and the disapear traits recessive.
What is meant by observed genotypes?
A phenotype is a physical characteristic. For a human an observed phenotype example would be hair colour (e.g brown) or eye colour (green). An observed phenotype is a physical characteristic that can be seen directly or indirectly (internal organs) caused by an individual's genotype.
What is the chi square test used for?
The chi-squared test is used to compare the observed results with the expected results. If expected and observed values are equal then chi-squared will be equal to zero. If chi-squared is equal to zero or very small, then the expected and observed values are close. Calculating the chi-squared value allows one to determine if there is a statistical significance between the observed and expected values. The formula for chi-squared is: X^2 = sum((observed - expected)^2 / expected) Using the degrees of freedom, use a table to determine the critical value. If X^2 > critical value, then there is a statistically significant difference between the observed and expected values. If X^2 < critical value, there there is no statistically significant difference between the observed and expected values.
How can heredity be observed?
heredity is the process by which characteristics are transmitted from parents to the offspring.
How is the chi-square test used in genetic analysis?
Because Chi-squares are used to analyze and compare observed frequencies to expected frequencies, they can help trace the probability of an offspring receiving a certain phenotype and genotype from their parents.

How did your observed results compare to your expected results?
The observed results were in line with the expected results, indicating that the hypothesis was supported. This suggests that the experiment was conducted correctly and the variables were controlled effectively.
How do i find expected value in a martingale system?
The expected value of a Martingale system is the last observed value.
What is the genetic makeup of an individual trait or for all of his or her inherited traits- the observable or detectable characteristics?
Different Genotypes are observed by varying phenotypes in a population
What does supererogatory mean?
performed or observed beyond the required or expected degree
How do you find the deviation?
The deviation is the observed value less the expected value.
Is a newt a predator?
Newt Gingrich has been observed stalking and devouring the helpless offspring of welfare-queen mothers.
For many years TV executives used the guideline that 30 percent of the audience were?
165 = 33% ABC observed, 150/30% expected 140 = 28% CBS observed, 150/30% expected 125 = 25% NBC observed, 150/30% expected (500 less 430 is 70) 70 = 14% Cable observed, 50/10% expected Chi square test for goodness of fit (between the guideline and the sample) The Null is that the guideline and observed results have no significant difference, the Alternative is that they do have a difference. (3 degrees of freedom, 4 categories -1) gives a critical value of 7.82 at .05 significance The Chi test for this data is 14.32 so the Null is rejected and the Alternative is accepted.
