Question

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?

Answer 1

3

Step-by-step 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.
