Meosis Flashcards
2 types of meiosis
Reductional Division
Equational Divison
Diploid cell is reduced to Haploid
Reductional Division
Brief Resting Between T1 and P1 and no Duplication of chromosomes
Equational Divison
Similar genetic sequence
Homologous Chromosomes
Similar genetic sequence
Homologous Chromosomes
Homologous chromosomes aligned>Chromosomes crossover>Recombinant chromatids
Crossing Over
Crossing over(gene recombination)
prophase 1 and metaphase 1
Sister chromatids are now called sister Chromosomes
Anaphase 1
Division of the Cytoplasm
Cytokinesis
Two daughter cells
Telophase 1
Resting period between T1 and P2
Interkinesis
Four haploid daughter cells
Cytokinesis
Death of cells body
Apoptosis
Cause down syndromes because homologous chromosomes fail to seperate
Non-Disjuction
Four sister
Tetrad
