Question

6. (10 points) For traits that show incomplete dominance, describe the phenotype of the heterozygote.

Answer 1

Incomplete dominance means both the allele contribute for a trait . When the alleles are present homozygous condition then only one trait is expressed. When the alleles are present in heterozygous condition then both the allele contribute for that phenotype, its the blending of both trait.

We can explain incomplete dominance with flower colour . When red allele is present in homozygous condition then only red colour flower is present. When only white allele is present white colour flower is present. But both the allele present in heterozygous condition then pink colour flower is present. This is the blending of colour red and white .
