1
What type of cell(s) does meiosis start with?
Meiosis starts with a diploid cell (2n), typically a germ cell.
New cards
2
What type of cell(s) does meiosis end with?
Meiosis ends with haploid cells (n), which are gametes (sperm or egg cells).
New cards
3
How many divisions occur in meiosis?
Meiosis consists of two divisions, called Meiosis I and Meiosis II.
New cards
4
When does crossing over occur?
Crossing over occurs during Prophase I of Meiosis I.
New cards
5
What happens in crossing over?
Homologous chromosomes exchange segments of genetic material, leading to genetic recombination.
New cards
6
Why is crossing over important?
Crossing over increases genetic diversity by creating new combinations of alleles in gametes.
New cards
7
How many times is the DNA copied in meiosis? In which stage?
DNA is copied once, during the S phase of interphase, before meiosis begins.
New cards
8
What type of cell is made in meiosis?
Meiosis produces gametes (sperm and egg cells).
New cards
9
If you start with 46 chromosomes, how many chromosomes will the gametes have?
Gametes will have 23 chromosomes (haploid number).
New cards
10
Why do cells undergo meiosis?
Cells undergo meiosis to produce gametes for sexual reproduction, ensuring genetic diversity and maintaining a stable chromosome number across generations.
