• One parent• Creates clones• Parent gives entire genetic make-up to

offspring

Examples:Binary Fission – ProkaryotesMitotic Cell Division - Eukaryotes

Asexual Reproduction

Mitotic Cell Division in Eukaryotes

• Budding• Fragmentation• Vegetative Reproduction• Unfertilized eggs

Page 4: Reproduction in Cells. One parent Creates clones Parent gives entire genetic make-up to offspring Examples: Binary Fission – Prokaryotes Mitotic Cell.

Sexual Reproduction• Two parents contribute equal # of chromosomes• To do this need non-somatic cells– Gametes = reproductive cells (sperm and eggs)• Produced by Meiosis• Haploid cells (n)

– Have 1 full set of chromosomes

• Fertilization creates a diploid cell (2n)– Have 2 full sets of chromosomes– homologous pairs = chromsomes have same sstructure and genes

Page 5: Reproduction in Cells. One parent Creates clones Parent gives entire genetic make-up to offspring Examples: Binary Fission – Prokaryotes Mitotic Cell.

Questions• A cell has a diploid number of 16, what is the

haploid number?• A cell that has 12 chromosomes is going to

divide to produce cells for sexual reproduction. How many chromosomes will the sex cells have?

• An egg cell for a certain species has 20 chromosomes. How many chromosomes will it have after it is fertilized?

Meiosis

Page 8: Reproduction in Cells. One parent Creates clones Parent gives entire genetic make-up to offspring Examples: Binary Fission – Prokaryotes Mitotic Cell.

Prophase I• Chromosomes condense• Homologous pairs move together– Crossing over occurs (exchange of DNA between

homologous chromosomes) allows genetic recombination and variation among species

Page 9: Reproduction in Cells. One parent Creates clones Parent gives entire genetic make-up to offspring Examples: Binary Fission – Prokaryotes Mitotic Cell.

Metaphase I• Pairs move to center of

the cell (metaphase plate)

Anaphase I•Homologous pairs separate

Page 10: Reproduction in Cells. One parent Creates clones Parent gives entire genetic make-up to offspring Examples: Binary Fission – Prokaryotes Mitotic Cell.

Telophase I• Homologous chromosomes are completely

separated

• Cytoplasm splits into two cells (cytokinesis)• Haploid (n) cells

Page 12: Reproduction in Cells. One parent Creates clones Parent gives entire genetic make-up to offspring Examples: Binary Fission – Prokaryotes Mitotic Cell.

Prophase II• Spindle forms• No more crossing over• Chromosomes move towards metaphase

plate

Page 13: Reproduction in Cells. One parent Creates clones Parent gives entire genetic make-up to offspring Examples: Binary Fission – Prokaryotes Mitotic Cell.

Metaphase II• Chromosomes line up

in the middle of the cell

Anaphase II• Chromosomes split and move to opposite sides of the cell

Page 14: Reproduction in Cells. One parent Creates clones Parent gives entire genetic make-up to offspring Examples: Binary Fission – Prokaryotes Mitotic Cell.

Telophase II• Chromosomes at opposite sides of the cell• Nucleus reforms• Cells divide (cytokinesis)– Four haploid gamete cells
