Mating
Lab:
Purpose: To have hypothetical offspring with at least
4 other individuals
In the
class and calculate the probability of certain traits using a punnet
Square. Next, you will perform a Vulcan mating ritual
(pon farr) where
you
randomly pick an allele from the other person and they randomly pick
one of your
alleles. Then observe the traits of your
offspring. Have 8 kids per mate
Keep track of
the genotype of each kid. By the end of the activity, you will have 32 kids
Method:
Write down
your phenotype for the following characteristics:
Earlobe
attachment or unattached
Tongue rolling or not T
t
Cleft chin or smooth chin. C
c
Widow’s peak or not W w
Natural curl or straight hair N
n
Dimples or not
D d
Righty or Lefty R
r
Freckles or not
F f
Girl XX or
boy XY
For each
trait, make the genotype as alleles on two small pieces of paper.
Write your phenotypes now:
For each
mate you have draw nine punnet squares representing
each trait and
calculate
the Probability of each trait.
