bipinajith's proposal works as long as all of the allele= and alleles= entries are in the 2nd field in the input lines, and all of the allele= entries come after the alleles= entry, except that it doesn't put the requested "/" between allele= entries when more than one is present. It also provides an extra leading newline that wasn't requested.

The following should work as requested no matter what order they are in nor which fields contain allele and alleles entries even if multiple entries appear on the same line. It will also print multiple alleles= entries if they occur using a comma to separate subsequent occurrences:
Code:
awk -F ' *| *' 'function pr() { 
        if(r) printf("%s %s %s\n", r, p, s)
        p = r = s = ""
        n1 = 1
}
NF == 0 {pr()
         next
}
n1 {    n1 = 0
        r = $1
}
/allele/ {for(i = 1; i <= NF; i++) {
                if($i ~ /allele=/)
                        s = (s ? s "/" : "") substr($i, index($i, "=") + 1)
                if($i ~ /alleles=/)
                        p = (p ? p "," : "") substr($i, index($i, "=") + 1)        }
}END {   pr()}' input

As always, if you're using a Solaris system, use /usr/xpg4/bin/awk or nawk instead of awk.
