Monster Genetics Lab: Unleashing Genetic Potential

Monster Genetics Lab - 30 points Name____________________________ Date_________ Period_________ Background: Zandor is an Earth-like planet located in another solar system in another galaxy some 6.2 billion light years away. One of the creatures that inhabits this planet is called the Kremulak (Monstrousitus sargii). Kremulaks reproduce sexually and have diploid body cells and haploid gametes. Kremulaks are fierce predators and have many adaptations that allow them to take down prey and defend themselves from any creature bold enough to attack them. Kremulaks have variability in many of their traits but some traits are common to all members of the species. All normal, healthy Kremulaks have 6 legs, 3 eyes, 2 pairs of ears, 1 mouth, and 6 fingers/toes. Directions: ● Students will work in pairs. 1 student will be designated a male parent and the other will be the female parent. ● For each trait, students will flip a coin to determine which allele will go into the male and female gametes. ● Unless noted otherwise, Heads = dominant allele and Tails = recessive allele. ● In the spaces provided, write down the genotype and phenotype determined by the coin tosses. ● On the paper provided, use phenotypes for each trait to draw and color the Kremulak. Flip 1 coin to determine the sex of your Kremulak. X _______ Heads = X Tails = Y Trait 1: Teeth shape: Alleles: Very sharp (T) Very dull (t) Male_____ Female_____ Genotype__________ Phenotype___________________ * Heterozygotes have teeth in between sharp and dull. Trait 2: Claw length: Alleles: Long claws (C) short claws (c) Male_____ Female_____ Genotype_________ Phenotype_____________________ Trait 3: Coat color: Alleles: Green fur (G) Blue fur (g) Male_____ Female_____ Genotype_________ Phenotype______________________ Trait 4: Coat length: Alleles: Long coat (X) short coat (x) Male______ Female_____ Genotype________ Phenotype__________________________ Trait 5: Coat markings: Alleles: Black stripes (Z) Black spots (z) Male___ Female___ Genotype_______ Phenotype___________________________ Trait 6: Firebreathing: Alleles: Firebreather (F) Non firebreather (f) Male___ Female___ Genotype________ Phenotype__________________________ Trait 7: Spikes: Alleles: Spikes (S) no spikes (s) Male_____ Female_____ Genotype_______ Phenotype____________________________ * If monster has spikes, flip for trait 8 and trait 9. If no spikes, skip to trait 10. Trait 8: Spikes: Alleles: Long spikes (L) short spikes (l) Male_____ Female_____ Genotype______ Phenotype______________________________ Trait 9: Spikes: Alleles: Spikes all over (A) Spikes on head (a) Male____Female____ Genotype______ Phenotype______________________________ Trait 10: Eye color: Alleles: Red eyes (R) yellow eyes (r) Male____ Female____ Genotype_______ Phenotype_____________________________ *Heterozygotes have orange eyes. Trait 11: Ear shape: Alleles: Pointy ears (P) round ears (p) Male_____ Female_____ Genotype_______ Phenotype____________________________ Trait 12: Ear size: Alleles: Large ears (E) small ears (e) Male_____ Female_____ Genotype______ Phenotype____________________________ Trait 13: Nose type: Alleles: Long/Trunk-like (N) short/wide (n) Male____ Female____ Genotype_______ Phenotype___________________________ Trait 14: Horns: Alleles: 2 branching horns (H) 2 curved horns (h) Male___Female___ Genotype_______ Phenotype __________________________ Trait 15: Wings: Alleles: 2 Wings (W) no wings (w) Male_____ Female_____ Genotype_______ Phenotype___________________________ Trait 16: Humpback: Alleles: Humpback (D) no humpback (d) Male____ Female____ Genotype_______ Phenotype___________________________ Trait 17: Leg length: Alleles: Long legs (A) short legs (a) Male____ Female_____ Genotype_______ Phenotype___________________________ *Heterozygotes have medium sized legs Discussion Questions 1. What did the coin toss for each parent represent in this simulation? 2. What is the Principle of Dominance? 3. What is the difference between genotype and phenotype? 4. List three traits (and their genotypes) that your monster had that were homozygous dominant. 5. List three traits (and their genotypes) that your monster had that were homozygous recessive. 6. List three traits (and their genotypes) that your monster had that were heterozygous.
