Tju [1.3M]

Answer:

3

Explanation:

Male ; EeHh

Female ; EeHh

Then,

possible gametes for each = EH / Eh / eH / eh

where,

                            EH                    Eh                   eH                    eh

EH                      EEHH               EEHh              EeHH               EeHh

                     <em>   One eye            One eye         One eye          One eye</em>

<em>                         One horn          One horn        One horn        One horn</em>

<em />

Eh                      EEHh                 EEhh               EeHh                Eehh

                       <em>One eye              </em><em>One eye</em><em>         One eye          </em><em>One eye</em><em> </em>

                        <em>One horn            </em><em>Two horn</em><em>       One horn         </em><em>Two horn</em>

eH                     EeHH                  EeHh              eeHH                eeHh

                        <em>One eye             One eye         </em><u><em>Two eye</em></u><em>          </em><u><em>Two eye </em></u>

                        <em>One horn            One horn        </em><u><em>One horn</em></u><em>        </em><u><em>One horn</em></u><em> </em>

eh                     EeHh                   Eehh                eeHh                eehh

                      <em>One eye              </em><em> One eye    </em><em>      </em><u><em>Two eye</em></u><em>          </em><u><em> Two eye </em></u>

<em>                       One horn              </em><em>Two horn </em><em>       </em><u><em>One horn</em></u><em>         </em><u><em>Two horn </em></u>

<u><em /></u>

Therefore,

One eye, one horn:One eye, two horn:<u>Two eye, one horn</u>:Two eye,two horn

is,

9 : 3 : <em><u>3 </u></em>: 1

This ration proves that the above working is correct and is dihybrid cross.
