Answer the questions below after watching the video
What is the primary purpose of meiosis?
To repair damaged cells
To produce identical body cells
To contribute to genetic diversity
To create 46 chromosomes in each cell
How many chromosomes do human gametes have?
23 chromosomes
46 chromosomes
92 chromatids
46 chromatids
What happens during interphase before meiosis begins?
Chromosomes are reduced to 23
Cells divide into gametes
DNA is replicated
Crossing over occurs
How many times do cells divide during meiosis?
Once
Four times
Twice
Three times
What stages are duplicated in meiosis compared to mitosis?
Prophase, metaphase, anaphase, and telophase
Only anaphase and telophase
Interphase and cytokinesis
Only prophase and metaphase
What is crossing over and during which phase does it occur?
Exchange of genetic material in prophase II
Separation of sister chromatids in anaphase I
Exchange of genetic material in prophase I
Alignment of chromosomes in metaphase I
What is the result of meiosis in terms of cell number?
2 identical cells
4 genetically unique cells
1 single cell
8 daughter cells
Why do siblings with the same parents look different?
Due to mitosis
Because of crossing over and independent assortment in meiosis
Because they have different numbers of chromosomes
Due to nondisjunction
What is the significance of independent assortment in meiosis?
It repairs damaged DNA
It reduces the chromosome number by half
It contributes to genetic variation
It duplicates the chromosomes
What is nondisjunction?
An error in chromosome separation
The duplication of DNA
A process that increases genetic diversity
The exchange of genetic material between chromosomes
