In an animal assume that rough coat (R ) is domiant over smooth coat (r ) and the black (B) is dominant over white (b). Consider that these two pairs  of alleles  assort independently then  (i) What proportion of the offspring  from the cross `RrBb xx "RRBB"`  would be rough  and black ?  (ii) From the cross `RrBB xx rrBB` . how many progeny will be homozygous for both of the  characters ?
