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.

Millions in the human body. Each cell has 23 pairs of chromosomes that have genetic importance. 22 of these are autosomes and one sex chromosome. The 22 determine traits and sex chromosomes determine the gender-XX develops into female and XY develops into male.omatic cells (body cells) are haploid cells. They have 23 pairs of chromosomes. Reproductive cells (gametes) have half the normal number i.e. 23. This is because two gametes (one male and one female) have to fuse hence, restoring the original number of 23 pairs.
