Meiosis vs Mitosis Flashcards
(27 cards)
Where does meiosis happen?
In reproductive organs
Sexual reproduction
2 parents contribute half their genetic info. For their offspring, which are different than them
What is formed during fertilization?
Zygote
Gametes
Special cells made by each parent in order for sexual reproduction to occur
Fertilization
When the sperm and the egg combine and form a cell with 46 chromosomes
Egg
The maternal gamete
How many chromosomes do both the egg and the Sperm have together?
46 (23 each)
Sperm
The paternal gamete
Asexual reproduction
One parent produces offspring through cell division which results as an exact copy
Happens everywhere in body
Mitosis
One cell division
Mitosis
No chromosome crossover
Mitosis
Purpose is repair and growth
Mitosis
Duplicates DNA every time
Mitosis
Daughter cells have 46 chromosomes
Mitosis
Reproduction in bacteria (asexual)
Mitosis
2 daughter cells
Mitosis
From body cells
Mitosis
Happens only in reproductive organs
Meiosis
2 cell divisions
Meiosis
Chromosome crossover
Meiosis
Purpose is sexual reproduction
Meiosis
Duplicates DNA only before 1st division
Meiosis
Daughter cells have 23 chromosomes (haploid)
Meiosis
