having the ability to roll or curl the tongue up along both sides to form a tube is a dominant trait. which diagram represents the chromosomes in a person that does not have this ability?

Answer

Answer: There is no correct option shown in the provided content. A person without the tongue - rolling ability has a homozygous recessive genotype (hh). Since the options only show 'H' and 'h' combinations but no 'hh' combination is present among them.

Explanation:

Step1: Understand dominant - recessive traits

The ability to roll the tongue is dominant (represented by 'H'). Lack of this ability is recessive (represented by 'h').

Step2: Determine the genotype of non - rollers

A person without the ability must have a homozygous recessive genotype, which is 'hh'. But the given options do not have this combination.
