What do you mean by Chromosomes?

Chromosomes may be defined as the tiny, threadlike structures inside most cells of every organism, or living thing that carry the genetic information of an individual.

The allele for rolling or curling the tongue up along both sides to form a tube possesses a dominant trait that means either a dominant HH or Hh must be present as a genotype to represent the given phenotype of curl or roll tongue.

Purebred recessive genotype i.e. hh shows the absence of desirable phenotype.

Therefore, the diagram which represents the chromosomes in a person that does not have this ability is 2 chromosomes are labeled h and h.
