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 , calculate the probability of certain traits using a punnet
Square.
RANDOMLY PICK AN ALLELE CARD observe the traits of the offspring. Have 2 kids per mate
Keep track of the genotype of each kid. By the end of the activity, there will be 6 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
Blood type. AA or Ao
BB or Bo
AB
oo
internal ovaries XX internal testes XY.
(NOTE THAT internal organs do NOT determine Gender identity)
METHOD
1. Find 3 VULCANS and write down their phenotype for each trait. If they have the DOMINANT TRAIT like Freckles, you can DECIDE whether they are Ff or FF
a. person 1 Phenotypes:
person 1 Genotypes
b. person 2 Phenotype
person 2 Genotypes
c. person 3 Phenotype
person 3 genotypes
For each mate you have draw the punnet squares representing
each trait and
calculate the Probability of each trait and show your punnet square.
C DRAW A HYPOTHETICAL OFFSPRING THAT THEY HAVE BY DOING THE FOLLOWING:
Dd is DENNIS
dd is Pocky
We want to know what happens when DENNIS mates with Pocky:
step 1:
make DENNIS's allele cards
D card and d card =Dd
make Pocky's allele cards
D card and d card = dd
step 2
To make an offspring, place the DENNIS D and d card face down and randomly choose one.
place the Pocky cards face down and randomly choose one.
step 3: What offspring did you get? DRAW A PICTURE OF THEIR OFFSPRING
