Sexual reproduction is where genetic information from two organisms (father+mother) is combined ....
to produce offspring which are genetically different to either parent.
1 of 10
In sexual reproduction the mother and father produce ...
gametes (egg + sperm cells)
2 of 10
How many chromosomes does each gamete contain?
23. A gamete has half the number of chromosomes as a normal cell.
3 of 10
The egg cell (gamete) from the mother and the sperm cell (gamete) from the father then fuse together (fertilisation) to form a cell with...
the full number (46) of chromosomes. Half from each parent.
4 of 10
Sexual reproduction involves the fusion of male and female gametes. Because there are two parents, the offspring contain...
a mixture of their parents genes.
5 of 10
Why does the offspring contain features from both its parents?
because it has a mixture of chromosomes from its mother and father.
6 of 10
This mixture of genetic material produces ..... in the offspring.
variation
7 of 10
AN ordinary cell can make a new cell by simply...
dividing into two.
8 of 10
The new cell has exactly the same ... as the parent cell, this is known as asexual reproduction.
genetic information.
9 of 10
In asexual reproduction there is only 1 parent. There is no fusion of gametes, no mixing of chromosomes and no genetic variation between parent+offspring. The offspring are genetically identical...
to the parent, they are clones.
