Being a computer analyst, he wanted to be very thorough in organizing the facts concerning his family's physical traits. He remembered from his Biology class that one's outward appearance (phenotype) was determined by one's genotype (genetic makeup). He also remembered that each person carries 2 alleles for each trait, one allele from each parent. PART 1: Meet the Spud Family Mr. and Mrs. Spud are expecting their third tater tot. As they flip through their family photo album, they began to talk about what baby spud might look like. Would his/her hair be curly like the Curly Fries on mom's side or would it be straight like the French Fries on dad's side. Mr. Spud, remembering some of his college biology, decided to make some predictions as to what his child might look like. Being confident with his task at hand, he got out some paper and began writing down the traits of his entire family. following is his list. The TABLE 1. Phenotypes of the Spud Family. TRAIT 1* Child 2nd Child Mrs. Spud Mr. Spud (alleles) Ear Lobes (E, e) Mouth (L, V) Hair (С, С) Eye Color (B, b) Nose (X", X") Freckles (F, F') (girl) (boy) free free free attached full lips thin lips thin lips full lips wavy straight wavy straight blue brown brown blue long wide wide long red & black red & black red red As he started his list, Mrs. Spud ran to the kitchen and grabbed a potato from the pantry. She thought it would be fun to create a visual of her next child. But, Mr. Spud reminded her that first they must construct their family pedigree in order to determine which alleles they each had. He decided the easiest way to find out each person's genotype was to construct a separate pedigree for each trait. He started with each person's phenotype and then translated each phenotype into its corresponding genotype. He knew he be predict what the next "Spud" might look like. Meanwhile, Mrs. Spud went to the computer and got on the internet to determine the genetics behind each trait. Here is what she discovered about Potato Head genetics: 1. Free ear lobes (E) are dominant to attached ear lobes (e). 2. Thin lips (L) are dominant to full lips (1). able everyone's genotype but he was hoping that he would have enough information to determine his genotype as well as his wife's.
