Meiosis (7.2) Exam: 3 [week 5]
the union of two haploid cells typically from two individual organisms
a nuclear division process that results in four haploid cells
The process of meiosis produces genetically unique reproductive cells called gametes which have half the number of chromosomes as the parent cell
Gametes are Haploid
Prophase I:
Metaphase I:
Anaphase I:
Telophase I:
Diploid
Haploid
Prophase II:
Metaphase II:
Anaphase II:
Telophase II:
Haploid
Haploid
(also, recombination) the exchange of genetic material between homologous chromosomes resulting in chromosomes that incorporate genes from both parents of the organism forming reproductive cells
Prophase I
It creates new gametes → new genes
How different genes independently separate from one another when reproductive cells develop
Metaphase I
Responsible for the production of new genetic combinations in the organism along with crossing over
Mitosis produces two genetically identical “daughter” cells from a single “parent” cell
Meiosis produces cells that are genetically unique from the parent and contain only half as much DNA
Most cells in the body regularly go through mitosis, but some do so more often than others.
