Vedclass · Answer

(B) To determine the correct pair,we must look at the standard chromosome counts for these organisms as provided in the $NCERT$ textbook:$1$. Maize: Meiocyte $(2n) = 20$,Gamete $(n) = 10$.$2$. Potato: Meiocyte $(2n) = 48$,Gamete $(n) = 24$.$3$. Housefly: Meiocyte $(2n) = 12$,Gamete $(n) = 6$.$4$. Rat: Meiocyte $(2n) = 42$,Gamete $(n) = 21$.Comparing these with the options:- Option $A$: Maize meiocyte is $20$,not $17$.- Option $B$: Potato gamete is $24$. This is correct.- Option $C$: Housefly meiocyte is $12$,not $20$.- Option $D$: Rat gamete is $21$,not $19$.Therefore,the correct pair is Potato with $24$ chromosomes in its gametes.
