Reproduction

Question 1

What is sexual reproduction?

Answer 1

Involves the fusion of male and female gametes

Because their are two parents the offspring will contain a mixture of their parents genes

Question 2

Describe sexual reproduction in humans?

Answer 2

The mother and father produce gametes (egg and sperm)
I’m humans each gamete contains 23 chromosomes (half a normal cell)
The egg and the sperm then fuse together to form a cell with a full number of chromosomes
It produces offspring genetically different fro either parent but containing genes from both
This creates variation in the offspring

Question 3

What is asexual reproduction?

Answer 3

Where there’s only one parent
There’s no fusion of the gametes
No mixing of chromosomes and genetic variation between parents and offspring
The offspring are genetically identical to the partent (they’re clones)

Question 4

What happens to a cell during asexual production?

Answer 4

It divides in it two

Question 5

Describe asexual reproduction?

Answer 5

1) x shaped chromosomes have two identical halves
2) so each chromosome splits down the middle to form two identical set of half chromosomes and a membrane forms around each set
3) the DNA replicates itself to form two identical copies with complete sets of x shaped chromosomes

Question 6

What is asexual production used for?

Answer 6

Animals and plants growing and productif replacement cells

Bacteria and certain plants produce offspring this way

Question 7

What’s the main difference between sexual and asexual reproduction?

Answer 7

Sexual produces genetically different cells

Asexual produces genetically identical cells
