Question

during meiosis, two chromosomes did not separate correctly. what may result from this error?
variation
chromosomal mutation
gene mutation
trisomy

Explanation:

During meiosis, if chromosomes do not separate correctly (nondisjunction), it can lead to an abnormal number of chromosomes in the resulting gametes. Trisomy is a condition where there is an extra chromosome (three copies instead of two). Variation is a general term for differences. Chromosomal mutation can involve changes in chromosome structure. Gene mutation affects a single gene. Nondisjunction specifically can cause trisomy.

Answer:

trisomy
