Practice Reading: Fill in the Blanks (Dropdown) ID: #51252 Ants
Instructions
Ants  are  known  for  working  together,  operating  as  a  unit  for  the  good  of  the  colony.  But  not  so  fast,  say  researchers  from  the  Universities  of  Leeds  and  Copenhagen.  It  turns  out  that  ants  can  scheme  like  a  stage  mom.    say  that  some  ants  hide  out  to  ensure  that  their  offspring  become  child-bearing  queens  instead  of  barren  workers.  The    hypothesis  had  been  that  random  ants  were  fed  certain  foods  that  would  allow  them  to  develop  into  queens.  But  DNA  tests  on  five    of  leaf-cutting  ants    that  certain  males  have  a  better  genetic  chance  of  producing  royal  progeny.  Scientists  believe  these  rare  males  stay  anonymous,  and  thus  avoid  any  problems  with  other  ants  that  might  otherwise  lose  their  "one-for-all,  all-for-one"  attitude.  In  fact,  the  number  of  males    royal  genes  to  those  who  aren't  may  have  settled  at  a  low  ratio  through      which  cobbled  together  the  best  way  for  the  ant  gene  pool  to  expand,  while  at  the  same  time  keeping  the  lucky  males  hidden  from  their  possibly  jealous  rivals.
