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.

Gametes (sperm and ova) are haploid cells. The haploid gametes produced by most organisms combine to form a zygote with n pairs of chromosomes, i.e. 2 n chromosomes in total. The chromosomes in each pair, one of which comes from the sperm and one from the egg, are said to be homologous.Cells and organisms with pairs of homologous chromosomes are called diploid.or example, most animals are diploid and produce haploid gametes. During meiosis, sex cell precursors have their number of chromosomes halved by randomly choosing one member of each pair of chromosomes, resulting in haploid gametes.
