Explanation:
remember doing this a while back, got it right.
The statement that is true about Karen's abnormality is that she has aneuploidy. Details about aneuploidy can be found below.
What is aneuploidy?Aneuploidy is a chromosomal abnormality whereby an organism possesses a chromosome number that is not an exact multiple of the haploid number of that organism.
In humans like Karen, the haploid number of chromosomes in each gamete cell is 23. This means that the number of chromosomes that is expected to be in the somatic cells is 23 × 2 = 46 chromosomes.
However, according to this question, Karen has 47 chromosomes but no apparent abnormalities. This suggests that she posseses aneuploidy.
