Which statement is false for 'AA+XYY' condition?

Options

A. These are aggressive people with abnormal height but highly intellectual.
B. Condition is due to endomitosis duplication of Y- chromosome.
C. This condition is Supermale and also known as jacob syndrome.
D. They have criminal bent of mind.

Answer

To determine which statement is false for the 'AA+XYY' condition, we need to analyze the characteristics associated with this chromosomal arrangement, known as the XYY syndrome or Jacob's syndrome.

### Step-by-Step Solution:

1. **Understanding Chromosomes**:
- The notation 'AA' refers to autosomes, which are the non-sex chromosomes. Humans typically have 22 pairs of autosomes.
- 'XYY' indicates the presence of an extra Y chromosome in males. Normally, males have one X and one Y chromosome (XY).

2. **Total Chromosome Count**:
- In the case of 'XYY', the total number of chromosomes becomes 47 (46 normal chromosomes plus one extra Y chromosome).

3. **Characteristics of XYY Syndrome**:
- Individuals with XYY syndrome are often taller than average.
- They may exhibit increased muscle mass.
- There is a noted tendency towards aggressive behavior and some studies suggest a correlation with criminal behavior.
- Intelligence levels in XYY individuals are generally reported to be lower than average, with a wider range of intelligence.

4. **Identifying the False Statement**:
- When evaluating statements about XYY syndrome, we look for claims that contradict the established characteristics.
- A statement claiming that individuals with XYY syndrome are "highly intellectual" would be false, as research indicates that they typically have lower intelligence levels.

5. **Conclusion**:
- The false statement regarding the 'AA+XYY' condition is that individuals with this chromosomal arrangement are "highly intellectual."
