The chromosomes contain the physical material that is getting passed down to offspring Every species has a different number of chromosomes—doesn’t relate directly to biological complexity (gorillas/chimps have 48 chromosomes, hints at similarities to humans) Somatic Cells: make up the vast majority of cells in human body—tissues including brain, heart, skin etc. Contains two copies of each homologous pair (diploid) so 46 chromosomes Sex Cells (Gametes): ova/egg cells produced in ovaries, sperm/sex cells in testes. only have one copy (haploid) of each 23 chromosome for total of 23. “the evolutionary significance of how genetic information is split up and passed down” mitosis is cell division in somatic cells occurs for growth of new cells as well as repair/replacement of tissue. through mitosis one parental cell creates two identical daughter cells that have the exact same genetic information as parent 1. Interphase in this phase, DNA replicates itself in preparation for future splitting. loosely
