There are 2 types of reproduction:
2. Sexual Reproduction (9 phases)
~ Another name for eggsand sperm
~ They are haploid (In humans, that is 23 chromosomes)
~ They are sexual cells
~ They are produced by sexual reproduction
Sperm + egg = zygote
~ Meiosis I
~ Meiosis II
There are 92 chromosomes (46 pairs!!)
~ Prophase I
~ Metaphase I
~ Anaphase I
~ Telophase I
The exchangeof sections ofhomologouschromosomes in aTETRAD.
And the division continues!!!!
~ Prophase II
~ Metaphase II
~ Anaphase II
~ Telophase II
Interphase II – does not exist
** Don’t forget!! This process is now occurring in both daughter cells created during Meiosis I **
Important: 4 haploid gametes areformed.
