In the world of purple people eaters, one eye (E) and one horn (H) are dominant traits. Purple people eaters can also have two eyes (e) and two horns (h), which are recessive traits.
Perform a dihybrid cross among a male who is heterozygous for both traits and a female
who is heterozygous for both traits. Use the results for your prediction below.
HOW MANY TWO-EYED ONE-HORNED PURPLE PEOPLE EATERS ARE THERE?

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

                        One eye            One eye         One eye          One eye

                        One horn          One horn        One horn        One horn

Eh                      EEHh                 EEhh               EeHh                Eehh

                       One eye              One eye         One eye          One eye

                        One horn            Two horn       One horn         Two horn

eH                     EeHH                  EeHh              eeHH                eeHh

                        One eye             One eye         Two eye          Two eye

                        One horn            One horn        One horn        One horn

eh                     EeHh                   Eehh                eeHh                eehh

                      One eye               One eye          Two eye           Two eye

                      One horn              Two horn       One horn         Two horn

Therefore,

One eye, one horn:One eye, two horn:Two eye, one horn:Two eye,two horn

is,

9 : 3 : 3 : 1

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

if you listed your answers right then i believe your answer is b.
