Question

Consider a eukaryotic organism in which the normal diploid number is 10. Which of the following statements is TRUE?

a. A monosomic individual would have 9 chromosomes.
b. A double trisomic individual would have 12 chromosomes.
c. Both A and B.
d. Neither A nor B.

Answer 1

The true statements are that a monosomic individual would have 9 chromosomes and a double trisomic individual would have 12 chromosomes, since the normal diploid number is 10.

Step-by-step explanation:

Considering a eukaryotic organism with a normal diploid number of 10 chromosomes, we can analyze the statements provided. A monosomic individual is one that has lost a chromosome and therefore would have one chromosome less than the diploid number, resulting in 9 chromosomes (10-1=9).

On the other hand, a double trisomic individual has gained two extra chromosomes, so they would have a total of 12 chromosomes (10+2=12). Therefore, the correct answer is c. Both A and B.
