Def of asexual reproduction
Reproduction that produces an offspring from one single parent

Def of Independent assortment
Different genes are sorted interdependent of each other.
The order and events of the stages of meiosis
Interphase
Meiosis 1
Metaphase1
Anaphase1
Telophase 1
Cytokinesis
Prophase 2
Ḿetaphase 2
Telophase 2
Cytokinesis
Sources of genetic variation
Mutation, Crossing over
Compare/contrast mitosis and meiosis
Meiosis- Two divisions, 4 daughter cells, Haploid
Mitosis- One division, 2 daughter cells,Diploid
Compare/contrast asexual and sexual reproduction
Sexual needs two parents as asexual only needs 1
