Segregation of Mendelian factor (Aa) occurs during
A
diplotene
B
anaphase I
C
zygotene/pachytene
D
anaphase II.
Answer
anaphase I
Explanation
Solution
Segregation of Mendelian factor (Aa) occurs during Anaphase-I. The paired homologous chromosomes separate in meiosis-I so that each gamate receives one chromosomes of each homologous pair. During Anaphase-I chromosome divides at the point of centromere or kinetochore and thus two sister chromatids are formed, which are called as chromosomes.
