Question
Mendel's monohybrid and dihybrid ratios are hypothetical predictions which are not based on which of the following assumptions? Each allele is dominant or recessive Segregation is unimpeded Dependent assortment occurs. Fertilization is random A hypothesis that assumes no real difference between measured values (or ratio) and predicted values (or ratio) is called________ When the calculated P-value for this hypothesis is so small (smaller than a threshold alpha value like 0.01), the hypothesis needs to be accepted or rejected? Alternate hypothesis H_a; rejected Null hypothesis H_0; rejected Alternate hypothesis H_1; accepted Null hypothesis H_0; accepted The Chi-square test involves a statistical comparison between measured (observed) and predicted (expected) values One generally determines degrees of freedom as_____ the number of categories being compared one less than the number of classes being compared one more than the number of classes being compared ten minus the sum of the two categories the sum of the two categories Which below is the correct statement for the Chi-Square value The sum of ([the deviation of observed value from expected]^2-expected_value) for all the observed data. The sum of ([the deviation of observed value from expected]^2 + expected_ value) for all the observed data. The sum of ([the deviation of observed value from expected]^2/expected_ value) for all the observed data. The sum of ([the deviation of observed value from expected]^2 + expected_ value) for all the observed data. For a DNA sequence with 4 nucleotides (i.e., tetramer), how many possible DNA tetramers can you get? 4 16 64 256 1024 What is the sequence of events in a typical eukaryotic cell cycle? G1 to G2 to S to mitosis to cytokinesis G1 to S to G2 to mitosis to cytokinesis G1 to S to G2 to cytokinesis to mitosisExplanation / Answer
6) Mendel's monohybrid and dihybrid ratios are hypothetical predictions and they are not dependent on C) Dependent assortment occurs, as we all know the assortment is independent.
7) A hypothesis where there is no real difference present between real and predicted values is known as B) Null hypothesis H0 ; rejected. As the threshold alpha value is less then 0.01, when the predicted value is less then 0.5 we tend to reject the hypothesis assuming a particular confidance interval.
8) The Chi-square test involves a statistical comparison between measured and predicted values B) One less than the number of classes being compared.
9) Correct starement would be C) The sum of ([The deviation of observed value from expected]2 / expected_value) for all the observed data. 2 = [ ( n - 1 ) * s2 ] / 2 .
10) For a DNA sequence with 4 nucleotides possible DNA tetramers that we can get would be D) 256.
11) In a typical eukaryotic cell cycle the events that followa each other are B) G1 to S to G2 to mitosis to cytokinesis.
