A)
Anaphase I
Homologous chromosomes are separated.
B)
Metaphase I
Pairing of maternal and paternal chromosomes.
C)
Interphase I
A nuclear envelop encloses each haploid set of chromosomes.
D)
Prophase I
Non-homologous chromosomes are separated.
Correct Answer: A
Solution :
[a] Pair of anaphase I with their feature is correctly matched. Metaphase I: Spindle apparatus appear and the chromosomes are arranged on equatorial plate, with the centromeres towards the pole. Spindle fibres become attached to the centromeres of the two homologous chromosomes. Interphase: It is the time during which cell is preparing for division by undergoing both cell growth and DNA replication. Prophase I: It is the lengthy phase when compared with mitotic phase. It is subdivided into 5 sub-phases: leptotene, zygotene, pachytene, diplotene and diakinesis.
