What process is being discussed in this video?
Meiosis
View source
What do you learn about chromosomes and gametes by the end of the video?
Meiosis
halves chromosomes to produce gametes
View source
How many pairs of chromosomes are in a normal human cell?
23 pairs
View source
What is shown in the diagram of a normal human cell?
Four pairs of
chromosomes
View source
What type of cells contain single chromosomes?
Gametes
View source
How many single chromosomes does a human gamete contain?
23 single chromosomes
View source
Where does meiosis take place in humans?
In
reproductive organs
View source
What are the male and female reproductive organs called?
Testes
and
ovaries
View source
What happens to chromosomes in the first stage of meiosis?
All
chromosomes
are
copied
View source
How many times does the cell divide during meiosis?
Twice
View source
How many gametes are produced from one original cell in meiosis?
Four
gametes
View source
What is true about the genetic makeup of the gametes produced by meiosis?
They are
genetically
different from each other
View source
What do gametes contain in terms of chromosomes?
Single
chromosomes
View source
What is the term for the joining of male and female gametes?
Fertilization
View source
What happens to the number of chromosomes after fertilization?
It is restored to
normal
View source
How many chromosome pairs does a fertilized egg contain?
23
chromosome pairs
View source
What process occurs after fertilization?
The new cell divides by
mitosis
View source
What is formed as the embryo develops?
Different
cell types
View source
What types of cells are mentioned as examples of differentiated cells?
Nerve cells
and
muscle cells
View source
What are the stages of meiosis relevant to the AQ8 specification?
Meiosis occurs in
reproductive organs
Chromosomes
are copied
Cell divides into two
Each cell divides again
Produces four
genetically
different
gametes
View source
What is the relationship between meiosis and fertilization?
Meiosis halves the number of
chromosomes
Fertilization restores the full number of chromosomes
Gametes
join during fertilization
View source
What happens to the fertilized egg after fertilization?
Divides by
mitosis
Forms an
embryo
Cells differentiate into
various
types
