Q. In frog chromosome number is reduced half:

EAMCETEAMCET 2005

Solution:

Each primary oocyte undergo two maturation divisions, first meiotic and the second meiotic division. In the I-meiotic division, the primary oocyte divides into two unequal haploid daughter cells-a large secondary oocyte and very small first polar body. In II-maturation division, the first polar body may divide to form two secondary polar bodies. The secondary oocyte again divides into two unequal daughter cells, a large ootid and a very small second polar body. The ootid grows into a functional haploid ovum. The 1 meiotic division is reductional and II meiotic division is equational division.
