Question
Using chromosomal analysis, a biologist working on a prototype can count and examine an individual's chromosomes. This technique helps a biologist to a identify the total number of gene defects in an individual. b predict the number of possible variations of a gene. c compare physical similarities between fraternal twins. d detect an unusually large amount of extra genetic material.

Using chromosomal analysis, a biologist can:
**d detect an unusually large amount of extra genetic material.**
Chromosomal analysis (such as karyotyping) allows scientists to examine the structure and number of chromosomes in an individual, which can help in identifying chromosomal abnormalities such as aneuploidy (abnormal number of chromosomes) or structural changes (like duplications or deletions of chromosomal segments). This technique is particularly useful in detecting conditions such as Down syndrome, which is caused by an extra chromosome 21.
