J, K, L & D , B are males

Then from the above conditions,

All of the given statements are true.

In the first column, 17 - 11 = 25 - 19 = 6.
In the second column, 12 - 6 = 34 - 28 = 6.
Let the missing number in the third column be y.
Then, y - 8 = 19 - 11 = 8 or y = 16.

The correct pattern is +4,+7,+10,+13,+16
So, 36 is wrong term and it must be replaced by 25+13=38

If virus is K in 1hr i.e 60 min
then in 57 min it was K/2 as it doubles every 3 minutes
=> In 54 min it was K/4.
At 54 minutes it was K/4.

As,

 A→+2C

 F→+2H

Similarly,

 $$\begin{gathered} K→+2M \\ T→+2V \end{gathered}$$

The first letters of the terms are alternate.
The sequence followed by the numbers is +2, +3, +4,....
The last letter of is three steps ahead of the last letter of the preceding term.

Since T is the brother of Q
Therefore, P is the father of T
but S is the wife of T.
Hence, S is the daughter-in-law of P.

Q is the son of R but R is not the mother. So, R is the Father of Q. P is married to R 

So, P is the wife of R and the mother of Q, X is the daughter of P and hence of R and so she is the Sister of Q, Y is the brother of R and Z is the brother of P. 

There are two females only — mother P and daughter X
