EBIO 1210 Chapter Notes - Chapter 10: Centromere, Mendelian Inheritance, Multicellular Organism
Document Summary
Parents endow their offspring with coded information in heredity units in the form of genes. In animals and plants, reproductive cells called gametes transmit genes from one generation to the next. Humans have 46 chromosomes in somatic cells. A gene"s specific location along the length of a chromosome is called a gene"s locus. In asexual reproduction, a single individual is the sole parent and passes copies of tis genes to offspring without fusion of gametes: give rise to a genetically identical clone. In sexual reproduction, 2 parents give rise to offspring with genetic variation. Meiosis and fertilization"s timing in the life cycle varies based on species: can be grouped into 3 main life cycles, animals, 2. The stages of meiosis there are 2 consecutive cell divisions, meiosis 1 and meiosis 2, producing 4 haploid daughter cells sister chromatids makeup one chromosome and and the two chromosomes were inherited form each parent (homologous pair)
