Document Summary
Key words mitosis meiosis gamete zygote diploid (2n) haploid (1n) preformation. Principle of independent assortment locus (plural: loci) gene alleles homozygous heterozygous dominant allele recessive allele genotype phenotype. Dna can control three things: (control protein synthesis, replicate itself, mutation) Mitosis: occurs in somatic cells, produces two identical daughter cells, 46- chromosomes is the diploid (2 end number, variation is due to errors in chromosome division and or mutation. Meiosis: occurs in sex cells, four daughter cells are produced. each 23 chromosomes haploid ( 1 end number, produces 4 different daughter cells through division and chromosome number reduction, solves the problem of maintaining karyotype structure in sexual recombination. Mid century ideas: gregor mendel (1822-1884) moravian monk. Where he went to college: mendel"s monastery in old brno. He began famous research and the crossing of plants: monks of the monastery. All books important up to that time: mendel"s pea garden. Why do we get offspring"s with different traits.
