because for parents to get a male child it should always be "XY" females always have XX chromosomes and males XY so obviously males will give the "Y" while females will be "X"
"XX" and "XY" are sex cells not chromosomes :) I hope you got it ! :)

Can someone explain me this question!!! Freakin WORST!!!!!!!View attachment 12737
4) B- we have to use the periodic table for this question. Element S is argon, so using the periodic table, the only logical answer is B, since the next element 'K', neither has one more electron in it's outer shell, nor is the same group or period as argon.
