The diagram below shows the body of a hen with the position of the
ovary and the oviduct in her abdomen. The hen has only got one ovary and one
oviduct. This is the same for most species of birds.
 The labels A, B, C
and D on the oviduct show the position of the egg and the time it has taken to
travel down the oviduct.
Below are four diagrams showing the egg at four stages of its development:
| 1. Which
stages of development 1, 2, 3 or 4 will be found at position A and
position D? |
At A= |
| At D= |
| 2. Where
will the hen's egg be fertilized by the cock's sperm? At position A, B,
C or D? |
|
| 3. On
the egg at stage 3, what is the part labelled X? |
|
| 4. On
the egg at stage 3 there are thick strands of albumen on each side of
the yolk. What do these strands do? |
