Meiosis Flashcards
Why do we need Meiosis?
mandatory for sexual reproduction.
What is Meiosis?
A form of cell division in gametes and halves the number of chromosomes. Used to make new sex cells.
What type of cell undergoes meiosis?
Germ cells
What are somatic cells and give an example.
all human cells ex. white cells
During meiosis, the chromosome number ____
Reduces
Meiosis produces ___ reproductive cells called ___
4, Gametes
Most multicellular eukaryotes form specialized reproductive cells by
A type of asexual reproduction when the cell divide in half.
Genes are exchanged between homologous chromosome during the process called
Crossing over.
The random distribution of homologous chromosomes during meiosis is called
Budding
In humans, gametes join during the process called ____ to form a diploid zygote
Fertilization
Homologous pairs of chromosomes move to opposite poles during
Anaphase 1
Spermatogenesis produces
Four haploid cells.
Sexual reproduction may have originated as a way for cells to
Shuffle genetic material
In plants, the sporophyte generation produces ____ spores through meiosis
Haploid
This organism would have how many homologous pairs of chromosomes?
10
Skin cells are continually bring rubbed off and replaced. How many chromosomes will be contained in each new skin cell that is replaced?
10
This replacement occurs through the process of
Mitosis
The female of this organism has an ovary. The number if chromosomes in each of the cells that make up the ovary would be
10
The mature eggs of this female would contain how many chromosomes?
5
Oogenesis ultimately give rise to _____ with the _____ number of chromosomes .
One ovum, haploid
