Question

question 30
an error in meiosis (or mitosis) leading to the wrong number of chromosomes is called
point mutation
nondisjunction
oopsy
replacement

Explanation:

• Point mutation: A change in a single nucleotide base in DNA. It doesn't directly lead to a wrong number of chromosomes.
• Nondisjunction: Occurs when chromosomes fail to separate properly during meiosis (or mitosis). This results in daughter cells with an incorrect number of chromosomes.
• Oopsy: Not a scientific term related to chromosome number errors in cell division.
• Replacement: A general term that doesn't specifically refer to the error in chromosome number during cell division.

Answer:

B. nondisjunction
