M1 genetic
sorted randomly, we can observe how alleles are passed on randomly (50/50 chance) and how the combination of alleles determines physical traits using a simple coin toss.
1. Make sure that you have read the assigned text reading and the module notes before beginning this activity.
2. Follow the instructions on the Traits Worksheet.
3. You will need a coin to complete this activity. For each trait you will flip your coin TWICE and record each allele (heads or tails).
4. The first toss represents the allele that Mom passes on while the second toss represents the allele that Dad passes on.
5. In your first two coin tosses, you will determine if your child is male or female. Heads represents the X chromosome, while tails represents the Y chromosome.
6. In all other coin tosses, dominant phenotypes will be represented by heads and recessive phenotypes will be represented by tails.
7. The combination of dominant and recessive “alleles” will determine the facial phenotypes in the progeny (your child.)
8. Using the Traits Worksheet, complete the table and submit your work in the appropriate dropbox.
