Coal mining produces not only air pollution but solid waste; ash and flue - gas desulferization sludge ( look it up ), which contains toxic arsenic and radioactive uranium among other heavy metals.

Since you forgot to put capital letters i assume it's like this:
1)A <span>Cross between YyLl (heterozygous parent with dominant traits) and yyll (homozygous parent with recessive traits).
</span><span> 2)offspring YyLl: 400, Yyll: 100, yyLl: 100 and yyll: 400
</span>The recombinant offspring are allele combinations that are not directly inherited from the parents.
The parents combinations:<span>YyLl and yyll,
</span>The recombinant combinations: Yyll and yyLl
The other types are exacly like the parents so they are not recombinant.
answer: Yyll and yyLl
