VULCANS are a logical species where emotions play no role in producing offspring. All offspring are the result of in vitro fertilization. They form no attachments with their mates.
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 CARD from the other person and they randomly pick
one of your allele CARDS FOR ANY PARTICULAR TRAIT.
Then observe the traits of your offspring. Have 2 kids per mate or have 4 kids with one other mate
Keep track of the genotype of each kid. By the end of the activity, you will have 4 kids
Method:
Write down your phenotype for the following characteristics:
Earlobe attachment EE, or Ee. unattached ee
Tongue rolling TT or Tt no tongue rolling tt
Cleft chin CC or Cc no cleft cc
Widow’s peak WW or Ww. straight hairline ww
Natural curl. NN. straight hair nn. wavy Nn
Dimples DD or Dd no dimples. dd
Righty RR or Rr. lefty rr
Freckles FF or Ff no freckles ff
internal ovaries XX internal testes XY
METHOD
For each trait, make the genotype as alleles on two small pieces of paper.
Write your phenotypes now:
For each mate you have draw the punnet squares representing
each trait and
calculate the Probability of each trait.
