Genetics NCEA Level 1- 90948
  1. Cell division
    1. Mitosis for growth and repair. 46 chromosomes in each cell. 2 genetically indenticaldaughter cells.
      1. Meiosis produces gametes needed for sexual reproduction. 23 chromosomes in each cell. 4 genetically unique daughter cells.
      2. DNA, chromosomes, genes and alleles
        1. DNA, a molecule found in the nucleus of cells made of nucleotides, which codes for an individual's genes. It can self-replicate.
          1. Nucleotide
          2. Chromosomes, thread-like structures made of wound up DNA. Come in pairs 46 in each human cell
            1. Genes, a section of DNA that codes for a protein.
              1. Allele, an alternative form of a gene can be dominant or recessive. Each characteristic has 2
              2. Reproduction
                1. Asexual, advantages- fast,easy, disadvantages-no variation
                  1. Sexual, advantages- variation, disadvantages- slower, harder
                  2. Variation
                    1. Causes- Sexual reproduction, meiosis (random assortment), mutations, environment.
