Properly create a file with tab when doing loop

I have this command line:

while read line
do 
echo $line >> Ho
grep -c "0/1/0" file_$line\.hwe >> Ho
done < my_file

Which will give me something like that:

ID1
689
ID2
747
etc.

I was wondering how I can make the loop so that the ls and grep command print on the same line instead of different lines. Here is what I want to obtain:

ID1  689
ID2  747
etc.

Any clue? Thanks!

Really, just:

while IFS= read -r line; do 
   echo "$line"$'\t'"$(grep -c "0/1/0" "file_$line.hwe")"
done < my_file >> Ho

or maybe:

while IFS= read -r line; do 
   printf "%s\t%s\n" "$line" "$(grep -c "0/1/0" "file_$line.hwe")"
done < my_file >> Ho

But still you could:

while IFS= read -r line; do 
   echo "$line" 
   grep -c "0/1/0" "file_$line.hwe"
done < my_file |
paste -d $'\t' - - >> Ho
