Meiotic Cell Division Flashcards
Heredity
Is The Transmission Of Traits From Parents To Offspring (From
One Generation To The Next Generation)
Meiotic Cell Division Is The Type Of Cell Division That Forms
Haploid (1N) Gametes
A Trait
Is An Inherited Characteristic
Sexual Reproduction
Occurs When Two Individuals Of Different Sexes Combine Their
Genomes To Produce Offspring
Meiotic Cell Division Occurs In Sexual Reproductive Organs Of
Diploid (2N) Species And Produces Genetically-Variable Haploid
(1N) Gametes
Meiotic Cell Division Ensures That Sexually Reproducing Species Maintain
A Constant Number Of Chromosomes Across Generations
Meiotic Cell Division Ensures that?
Your Great Grandparents, Grandparents, Parents, You, Your Children, And Your Grandchildren All Have 46 Chromosomes In The Nucleus
Meiotic Cell Division Increases
Genetic Variation In Populations
All Multi-Cellular Organisms That Reproduce Sexually Need Both
Mitotic Cell Division & Meiotic Cell Division To Function As Coherent Biological Systems
Mitotic Cell Division Enables The
Embryo To Form The Human Body
* Adult Stem Cells To Supply Your Body With
New Cells
Meiotic Cell Division Enables Your Body
To Produce Genetically Variable Haploid
(1N) Gametes
DNA Synthesis (DNA Replication) Precedes
Meiotic Cell Division As It Does Mitotic Cell Division
Meiotic Cell Division (Meiosis) Consists
Of
Two Sequential Cell Division Events
Called Meiosis I & Meiosis II
Meiosis I & II Each Consist Of Five
Stages Like Mitosis -
*Prophase
* Prometaphase
* Metaphase
* Anaphase
* Telophase
Meiosis I is
The First Meiotic Cell
Division Event
Meiosis I
The Spindle Separates Each Pair Of
Duplicated Homologous Chromosomes
Cytokinesis Separates The Germ-Line
Cell To Produce Two Cells
The Nucleus Of Each Daughter Cell
Has -
* 2 Maternal Or 2 Paternal Sister Chromatids
For Chromosomes 1-22
* XX In Females
* XX Or YY In Males
