Question

I was wondering if my answer of 18.25 was correct

Answer 1

1° Step

write the question data

Black fur (W), Fawn fur (w)

Long ears (E), short ears (e)

2º Step

Make the cross between the heterozygous parents

WwEe x WwEe (Punnett square)

3° Step

The phenotypic proportion is equal to:

9:3:3:1

Being: 9 with W_E_ (genotype), being black fur and long ears pugs;

3 with W_ee and wwE_, being black fur and short ears and fawn fur and long ears;

1 with wwee, being pugs with fawn fur and short ears.

Therefore, the proportion of offspring with fawn fur and long ears (wwE_) is

$\frac{3}{16}$

, equals to 18,75 % of the offspring.
