Question

the diagram shows meiosis taking place in a cell. what type of chromosomal abnormality occurred? translocation nondisjunction deletion substitution

Explanation:

• Translocation: Involves the exchange of genetic material between non - homologous chromosomes. This is not depicted in the diagram.
• Nondisjunction: Occurs when chromosomes fail to separate properly during cell division (such as meiosis). In the diagram, it appears that chromosomes did not separate evenly, leading to an abnormal distribution of chromosomes in the daughter cells.
• Deletion: Is the loss of a segment of a chromosome. There is no indication of a segment being lost in the diagram.
• Substitution: Is a type of mutation at the nucleotide level (not a chromosomal - level abnormality as shown in the diagram).

Answer:

Nondisjunction
