Continuous frame mortar guards are. desirable for masonry walls to avoid screw fastener interference. with the mortar. An effective mortar guard made from an. ordinary 1â (25 mm) x 2â (51 mm) stud, fastened to the back. side of the frame can also be used. Check with both the frame.
Gametes are always haploid. Gametes should be haploid for maintaining the chromosome number of the species.This is achieved by meiosis the reduction division in germ cells. Meiosis is reduction division that occurs only in germ cells where gametes are produced with half the chromosome number to that of the parent cell.ametes should be haploid for maintaining the chromosome number of the species.This is achieved by meiosis the reduction division in germ cells.

Haploid cells are produced by meiosis. During meiosis, the chromosome number is halved from the diploid number to the haploid number. Similar to mitosis, in meiosis also, DNA replication takes place in the parent cell during the interphase.After this, two cycles of nuclear divisions and cell divisions take place. Diploid cells are genetically identical to the parent cell, and haploid cells are not genetically identical to the parent cell. â¢ Haploid cells are important in sexual reproduction, and diploid cells are important in growth, asexual reproduction and genetic stability.
