The cells of the zygote then divide by mitosis (which does not change the ploidy level) to produce an adult organism (still 2n) of the next generation. You will use microscopy to study the process of cell division. Many organisms package these cells into gametes, such as egg and sperm. The recessive allele is only expressed when the dominant allele is not present, Traits located on the first 22 pairs of chromosomes (autosomes) and only expressed when both alleles are recessive (cc); ex. Give the formula and name of a square-planar complex of Pt2+^{2+}2+ with one nitrite ion (NO2_2^2, which binds to Pt2+^{2+}2+ through N), one chloride ion, and two ammonia molecules as ligands. The nuclear division that forms haploid cells, which is called meiosis, is related to mitosis. Errors in meiosis are the cause of chromosomal abnormality. Which one do you think is correct? Learn about life and living organisms in our biology simulations for Majors.
