Document Summary
Carry same inherited characteristics: sex chromosomes = x and y chromosomes. All other chromosomes are called autosomes: diploid cell = any cell with two chromosomes sets. If they did germ cells would be diploids so when they combined that would be too many cells: meiosis reduces the amount of chromosomes->why gametes have 23, meiosis occurs in germ cells during the production of gametes. After fertilization, the diploid zygote divides by mitosis: plants and algae undergo alternation of generations diploid and haploid stages that are multicellular, sporophyte = multicellular diploid stage, spores = haploid cells produced by meiosis in the sporophyte. 14. 1 mendel used the scientific approach to identify two laws of inheritance.
