Name _______________________________________ Dragon Meiosis
Go to the following website:

1. Dragons have five distinct traits:
a. ______________________________________
b. ______________________________________
c. ______________________________________
d. ______________________________________
e. ______________________________________
2. Roll your mouse over each parent cell to see their chromosomes and
genes. Draw and label the chromosomes and genes for the male and the
female below. This is the genetic makeup or genotype of the two
parents. Use colored pencils.
Male
Female
3. Click the stage button to go through meiosis step by step. On the back
of this page, draw the stages of meiosis for either the male or the
female. Make sure you name each phase and draw an arrow to the
phase it is leading into. Use colored pencils.
Note: Dragons are like birds where males are XX and females are XY.
In humans, males are ___________ and females are __________.
4. Go through the stages for the opposite sex- it looks very similar so you
do not have to do the drawings.
5. Use the reading in the blue section:
During meiosis, each parent cell divides __________ to form
_______ gametes, cells having ________ the number of chromosomes as the
original cell.
Are all the gametes the same? _________
Since each gamete has half the number of ______________, a
gamete from ________________ can be combined with a gamete from
____________________ to create a new complete cell.
5. Now you will choose one gamete from the male (father) and one from
the female (mother). Roll your mouse over the male and female gamete
that you are going to use for fertilization. Draw and label the
chromosomes and genes for the male and female gamete below. Use
colored pencils.
Male gamete
Female gamete
6. Click on the two gametes, and now you can run ____________________.
7. Draw and label the offspring’s chromosomes and genes are by rolling
over the offspring’s cell. Use colored pencils.
