Question

in which type of inheritance pattern do heterozygotes show an intermediate phenotype?
a.) autosomal recessive
b.) codominance
c.) incomplete dominance
d.) autosomal dominant

Explanation:

• Autosomal recessive: Recessive allele needs two copies to show. No intermediate phenotype.
• Codominance: Both alleles express fully. No intermediate, both traits shown.
• Incomplete dominance: Heterozygote has intermediate phenotype. Like red and white flower making pink.
• Autosomal dominant: One dominant allele shows trait. No intermediate.

Answer:

C. Incomplete dominance
