QUESTION

The number of linkage groups in cattle are?

OPTIONS

(A) 20
(B) 30
(C) 18
(D) 25

ANSWER

(B) 30

EXPLANATION

Cattle have 30 linkage groups, corresponding to the 29 autosomes plus the X chromosome; the Y chromosome is homologous to X for part of its length but is not counted as an additional independent linkage group in the conventional figure. The other numbers therefore do not represent the standard linkage-group count.
