Read statements A-D, and select the correct option. A. Mitosis produced two identical daughter cell. B. Meiosis introduces variation due to gene exchange. C. After anaphase, the chromosome has two chromatids. D. Anaphase I is responsible for the reduction in chromosome number of gametes.
Options
- AAll are correct
- BA , B , C are correct
- CA , B , D are correct
- DC , D are correct
Correct answer
C. A , B , D are correct
Step-by-step solution
Mitosis is an equational division in which one cell divides to form two identical daughter cells. Meiosis produces genetic variation due to crossing over which occurs during prophase I of meiosis. During anaphase centromere splits and two chromatids are separated and starts moving to opposite poles. During anaphase I, the homologous chromosome moves to opposite poles, hence reduction in the number of chromosome happens.
