Question

Please consider Figure 8.8 (attached below) in the textbook (Figure 8.7 in the 4TH edition), which contains data that were obtained by Clegg et al., is redepicted from their paper that was published in 1980, and for which information is provided on pp. 300-302 in the textbook (pp. 289-291 in the 4TH edition textbook); assess comprehensively the lowercase-Roman-numeral-labelled statements that appear immediately below; and click the uppercase-letter-labelled response that is presented below and conveys the most accurate information.

i. At generation 0, the populations were characterised by D = -1 or D = 1.

ii. The D value changes could have resulted from processes including crossing over during meiosis.

iii. The D values changed by the factor (1- r) each generation.

iv. At generation 0, the populations were characterised by D = -0.25 or D = 0.25.

v. At generation 0, the populations were characterised by extreme values, representing complete linkage disequilibrium.

 

Question 1 options:

 

A) 

Statements ii through v inclusive convey accurate information.

 

B) 

Statements i and v convey accurate information.

 

C) 

Statement i conveys accurate information.

 

D) 

Statements ii and iii convey accurate information.

 

E) 

No statements convey accurate information.
