Answer 1

${ \huge \bf { \mid{ \overline{ \underline{Answer}}} \mid}}$

In meiosis chromosome number leads to Half of the original value & formation of Haploid gametes.

$\huge{\bold{\underline{Additional\: Points:-}}}$

• The term Meiosis was coined in the year 1905 by Farmer & Moore.

• It (Meiosis) only Occurs in Sexually reproducing organisms.

• Meiosis results in the Formation of Haploid Gametes.

• Meiosis is Divided in two phases :- Meiosis I & Meiosis ll.

• Meiosis l is characterized by Reductional Divison.

• Meiosis ll is characterized by Equational Division.

• Due to Meiosis Variations occur in a Species or Population.

• Meiosis helps to maintain the Chromosome number in a particular species In Sexual reproduction.

• It (Meiosis) also helps in the Formation of Gametes in Sexually reproducing organisms .

• Each Meiosis (Meiosis l & Meiosis ll) has 4 stages in it. I.e. Prophase, Metaphase, Anaphase & Telophase.

• The Prophase - l of Meiosis l is divided into Further 5 sub - stages I.e Leptotene, Zygotene, Pachytene, Diplotene & Diakinesis.

Note:-

• Prophase ll of Meiosis ll doesn't have sub - stages like Prophase l of Meiosis l.
