the cellular basis of reproduction and inheritance

two daughter cells are created during cell division and identical copies are made that genetically identical to each other.

  • it duplicates the chromosomes that carry most of the genetic information

asexual reproduction is where the cell creates a clone/genetic replicas of itself by one parent/cell, creates a clone

  • the process called mitosis

sexual reproduction is where the offspring is a fusion of gametes, egg and sperm.

  • the gamete has half of the chromosomes as the parent cell, the chromosomes have contain a unique combinations of genes

  • offsprings of sexual reproduction aren’t clones/ identical to the parents and creates variation among offspring

  • the process called meiosis

binary fission (dividing in half)

chromatin- consists of an equal amount of DNA and proteins

the cell cycle for dividing cells can be broken into three subphases

  • G1 (first gap), S (DNA replication), G2 ( second gap)

then the cell is getting ready to divide in goes through interphase, which synth

mitosis can be broken down into 5 main stages

  • prophase

  • prometaphase

  • metaphase

  • anaphase

  • telophase
