Question

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_0; rejected Null hypothesis H_0; rejected Alternate hypothesis H_0; is accepted Null hypothesis is L_0; accepted The Chi-square teat involve, 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 I he two categories the turn 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 ail 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]^3 *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 mitosis

Explanation / Answer

6) Mendel's monohybrid and hybrid ratios are hypothetical predictions which are not based on which of the following assumptions?

Answer: C) Dependent assortment occurs

Mendel's hypothetical predictions are based on the following factors:

1) Each allele is dominant or recessive (Mendel's second postulate - Dominance / recessiveness).

2) Segregation is unimpeded (Mendel's third postulate - Random segregation)

3) Independent assortment occurs (the genes must be located on different chromosomes) (Mendel's fourth postulate - Law of Independent Assortment)

4) Fertilization is random.(Segregation & assortment of alleles during gamete formation & at fertilization occur randomly)
