Resuits Purpose: To demonstrate the principles of Mendelian genetics and sex determination, including the concepts of allele, phenotype, genotype, dominant, recessive, codominant, homozygous and heterozygous by creating a simulated baby. Table 1: Circle here whether you are the mom or dad and fill in the data below. Mom's Name Dad's Name Procedure: Baby's Name 1) Determine the genotype of the baby by flipping 2 coins. The 2 coins represent the parents. Flip the "Mom Coin" to determine an allele for her egg and the "Dad Coin" to choose an allele for his sperm. (Note that the sex of the baby is determined by dad alone. Boys are XY and girls are XX. Mom can give only an X but dad can give an X or a Ý chromosome.) Trait Allele from Mom Allele from Dad Genotype Phenotype Sex X Face Shape Chin Shape Chin Dimple Freckles Cheek Dimples Lip Thickness Eye Brows Eye Shape Eyelashes Ear Shape Ear Lobes Widow's Peak 2) Record the alleles which resulted from the coin flips and put "sperm and egg" together. Write down baby's genotype (XX or XY) for each trait in Table 1. Heads represents allele #1 and tails represents allele #2. 3) Record the resulting phenotype in Table 1 (Girl or Boy). Note: Dominant alleles are written with an uppercase letter and recessive alleles are written as lowercase letters. Dominant alleles mask the expression of recessive ones. Co-dominant alleles are written as uppercase letters with a subscript. Co-dominant alleles result in a phenotype that is blended. 4) Repeat steps 1, 2, and 3 for all traits and then draw, color, and name your creation. Remember that you are drawing a baby's face-not a child's or an adult's (no tattoos, pierced ears, mustaches, etc.) Hair Curliness (You may draw your baby here after completing the baby's traits in the next page).
