Cytokinesis :
Meiosis: 1 cell becomes 4 cells which are called gametes
Male gametes = _______________
Female gametes = _________________
The Difference
Meiosis is _____________________ twice _______________________ interphase in between.
Mitosis is in my________________, but Meiosis is in my ___________________!
Why Meiosis?
--Fertilization
–Union of ____________________________ (n)
–____________ is formed (2n)
•The chromosome number is _______________, so at fertilization there is
_____________________________________________________________
•Cuts chromosome ______________________________ ( 2n—n)
•Creates ________________________________________
•Makes offspring ________________
Meiosis Creates variation in 3 ways.
1. Law of Segregation:
2.
Law of Independent Assortment:
3. Crossing Over:
Mitosis or Meiosis
Diploid (2N)
•Cells ________________________________________________________________________
•Human body cells have ___________ chromosomes each = (diploid or 2N # is 46)
Haploid (N)
•Cells ________________________________________________________________________
•Human sperm & eggs have ____________ chromosomes = (haploid or N # is 23)
