Answer:
= 25 %
Explanation:
Given that :
the genotype attributed to trolls having one eye = (EE, Ee); that is homzygous dominant or heterozygote dominant for eye number
Likewise those that posses two eyes have (ee) ; that is homzygous recessive
Now; two heterozygous one eyed trolls are crossed ; we have :
Ee × Ee
The punnet square for this cross looks like what we have below:
E e
E EE Ee
e Ee ee
From the above cross; we have:
1 EE ---- (homozygous dominant ) indicating troll having one eye
2 Ee ---- ( heterozygote dominant ) indicating troll having one eye
1 ee ----- ( homozygous recessive ) indicating troll having two eyes
The genotypic ratio is 1:2:1
Thus; the expected genotype ratio of the two eyed offspring =
= 25 %
