Question 23

In pedigree charts, a completely filled - in square (for males) or circle (for females) is a standard symbol. This symbol is used to represent that the person (the individual represented by the square or circle) has the trait (usually a genetic trait) that is being tracked in the pedigree. The other options: a carrier (for recessive traits) is usually represented by a half - filled symbol; a person without the trait and not a carrier is typically an empty symbol; and just stating a person does not have the trait is not what a filled symbol means.

The sequence given is ACGGCT. Let's analyze the components of different molecules:

• Proteins are made of amino acids, and their structure does not consist of nucleotide sequences like ACGGCT.
• Sugars are carbohydrates with a different chemical structure and do not have nucleotide - like sequences.
• RNA contains the base uracil (U) instead of thymine (T). The given sequence has T, so it can't be RNA.
• DNA is composed of nucleotides with the bases adenine (A), cytosine (C), guanine (G), and thymine (T). The sequence ACGGCT has these DNA - specific bases (A, C, G, T), so it is likely part of a DNA molecule.

Answer:

A. That person has the trait.
