8-10. Despite the fact that the Vietnam War ended in 1975, remains of soldiers who died there are still being recovered. For this activity, assume that remains of an unknown soldier have been unknown, recovered and returned to the United States for identification. DNA fingerprinting was unknown in 1975, so there are no DNA fingerprints on record for this soldier. Based on other information, it is assumed that the body is one of 6 soldiers whose remains were never recovered, and DNA is obtained from parents of the missing soldiers (fortunately, they are still living), written above the wells. (Dotted lines have been drawn between parent groups to help you with identification.) 1 2 Soldier Jacksons Mom Dad 3 4 Santiagos Mom Dad 5 6 Gunthers Mom Dad 7 8 McBrides Mom Dad 9 10 Werners Mom Dad 11 12 Lees Mom Dad 13 To which family does this soldier belong? How do you know? Remember that each individual gets one "band" (allele) from each parent. Gunthers Are any of the individuals shown in the gel above homozygous for this allele? If so, which one(s)? Do any two individuals above have the same genotype? If so, which two?

A pea plant is heterozygous for both pod shape and color. I is the allele for dominant, inflated pod; i is the allele for recessive, constricted pod. G is the allele for dominant, green pod; g is the allele for recessive, yellow color characteristic. Suppose this plant is crossed with a homozygous pea with inflated, green pod, what will be the possible genotype of the offspring? Construct the Punnett square, then identify the following: 1. Parents' genes? 2. Parents' traits? 3. Genes (genotype)? 4. Shape, color? (phenotype)? 5. Genotypic ratio? 6. Phenotypic ratio?

Use the below pedigree chart to answer the following questions. Muscle type is not a sex-linked characteristic. Fast-twitch muscles (F) are dominant over slow-twitch muscles (f). a) Write the genotypes corresponding to each numbered person in the pedigree below. 1 - 2 - 3 - 4 - 5 - 6 - 7 - 8 - 9 - 10 - 11 - 12 - 13 - 14 - b) Can either individual #8 or 9 be homozygous? c) Explain the family relationship that #12 has with #2.
