Question 13 • FL-2002070-M/J Comprehensive Science 2

Which best describes the offspring of a curly-haired dog (CC) with a straight-haired dog (SS), assuming incomplete dominance?

Answer
A
All the offspring will be hairless.
B
All the offspring will have straight hair.
C
All the offspring will have curly hair.
D
All the offspring will have wavy hair.

Explanation

With incomplete dominance, a heterozygous offspring shows a blended trait between the two parents. Crossing CC (curly hair) with SS (straight hair) gives every offspring one C allele and one S allele, so all are CS. The blended phenotype is wavy hair, so all the offspring will have wavy hair.
