Mitosis and Meiosis

Quiz 6 Bio 111

What happens in Mitosis?

One parent cell divides to form two genetically identical daughter cells

Type of Asexual Reproduction

Budding- seen in Hydra plants

Interphase

G1, S, G2

G1

Metabolic activity and growth of cells 

S

Metabolic activity, growth, and DNA replication

G2

Metabolic activity, growth, preparation for cell division

M Phase (Mitotic Phase)

Mitosis

Cytokinesis

Mitosis

Distribution of chromosomes into two daughter nuclei

Cytokinesis

Division of cytoplasm

Mitosis

Prophase

Prometaphase

Metaphase

Anaphase

Telophase and Cytokinesis

Prophase

2 sister chromatids of 1 chromosome

Prometaphase

nuclear envelope breaks down

Metaphase

alignment of chromosomes on the equator of the cell

Anaphase

Sister chromatids to daughter chromosomes

Telophase and Cytokinesis

cells divide into 2

Meiosis

interphase: chromosomes are duplicated

meiosis 1: homologous chromosomes are separated

meiosis 2: sister chromatids are seperated

SEXUAL REPRODUCTION

Prophase 1

Diploid cells

crossing over takes place (chiasmata) which introduces genetic variation

Metaphase 1

independent assortment

Anaphase 1

homologous chromosomes separate

Telophase 1 and Cytokenisis

Cells are Haploid

cell divides into 2

No S phase between this and prophase 2

Prophase 2

Cells are haploid, NO crossing over

Metaphase 2

independent assortment, chromosomes line up in the middle of the cell

Anaphase 2

sister chromatids separate

Telophase 2 and Cytokinesis 2

cells divide into 4 haploid cells 

Diploid

two sets of chromosomes

Haploid

one set of chromosomes

How are Mitosis and Meiosis ll similar?

sister chromatids separate in each

What are the locations of crossing over called

Chiasmata
