MEIOSIS and MITOSIS

Vulcan Mating Ritual

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.

Homologous Chromosomes, Genetics and Mitosis vs Meiosis

You will review some notes on homologous chromosomes and also go over some basic Genetics concepts.  Further you will review the main concepts of Mitosis vs Meiosis as you review this video
