In Genetics,a Chi-Square Test Can Be Used to Determine ____

Question

In genetics,a chi-square test can be used to determine ____.
A) whether an organism with a dominant phenotype is homozygous or heterozygous
B) whether an allele exhibits complete or incomplete dominance
C) what the predicted outcome of a dihybrid cross will be
D) how closely actual results of a cross match the expected results
E) whether a trait is determined by one gene or many genes

Accepted Answer

A chi-square test is used to determine how closely actual results of a cross match the expected results, which can help determine if there is a significant difference and whether the deviation is due to chance or other factors. This test compares the observed data with the expected data to determine the probability that the differences between them are due to chance rather than significant differences in the genetic makeup.
