The question is incomplete as it does not have the options which are:
A) test cross
B) two-point test-cross
C) three-point test-cross
D) chi-square analysis
E) recombination frequency (r) calculation
Answer:
D) chi-square analysis
Explanation:
Chi-square analysis is a test which is used to study the relationship between the variables of a population. The Chi-square test is performed to test if the observed results are due to chance or is real.
To test this a null hypothesis is formulated which says that there is no relation between the variables. The chi-square test is used in various disciplines but in molecular biology, there are used in the linkage mapping and the Mendelian crosses.
Thus, Option-D is correct.
