Gene Monsters: Selective Breeding Name:_______________________________ Name:___________________________________ Block:______ MB or KH Before presenting to Ms. Healy: 1. Make sure your breeding chart is labeled and easily understood. 2. Label all special Gene Monsters with their name and highlight the genotype combinations that make the phenotype characteristics. Level 1 - The BALD CYCLOPS Characteristics: Bald (kk) , one eyed (ff) and unhorned (hh). Level 2- The BLUE-GREEN UNICORN Characteristics: One horn (II), bald (kk) green face (??), green arms (QQ, Qq), green body spot (PP, Pp), blue body (RR). Level 3- The RED DEVIL Characteristics: Red face (ss), red body (rr), red arms (qq), no body spot (pp), orange hair (mm), three horns (ii), both upper and lower fangs (O,o). 3. Be prepared to demonstrate sophisticated understanding to exceed standard. Possible questions. Do the F1 offspring look like either of the P1 parents? What observations can you make about the traits that were passed from the parents to the children? It has often been said that children often resemble their grandparents more than their parents. Is this true based on your three generations of gene monsters? Are there any characteristics that make all these offspring resemble each other? What are they? MS-LS3 Heredity: Inheritance and Variation of Traits MS-LS3-2: Develop and use a model to describe that sexual reproduction results in offspring with genetic variation. Emphasis is on using simulations to describe the cause and effect relationship of gene transmission from parent(s) to offspring and resulting genetic variation. LS3.A: Inheritance of Traits --Variations of inherited traits between parent and offspring arise from genetic differences that result from the subset of chromosomes (and therefore genes) inherited. (MS-LS3-2) DCI LS3.B: Variation of Traits In sexually reproducing organisms, each parent contributes half of the genes acquired (at random) by the offspring. Individuals have two of each chromosome and hence two alleles of each gene, one acquired from each parent. These versions may be identical or may differ from each other. (MS-LS3-2) DCI Exceeding Meeting Approaching Beginning Breeding chart is easily understood, all of offspring are linked to parents, breeding partners are identified and breeding model is completely accurate. Breeding chart is easily understood, all of offspring are linked to parents, and breeding model is completely accurate. Breeding chart is easily understood, all of offspring are linked to parents, and breeding model is mostly accurate. Breeding chart is not easily understood, offspring are not linked to parents, and breeding model has significant errors. P1 Generation: Two parents bred from heterozygous breeders A & B with 100% accuracy (20 correct genotypes & phenotypes). Student demonstrates a sophisticated understanding of inheritance of traits. P1 generation forms four offspring for the F1 generation. F1 forms four offspring for F2. F2 forms four offspring for F3. All genotypes and phenotypes are 100% accurate. At least one special Gene Monster was selectively bred (Bald Cyclops, BlueGreen Unicorn or Red Devil) and/or student demonstrates a sophisticated understanding of selective breeding. P1 Generation: Two parents bred from heterozygous breeders A & B with 100% accuracy (20 correct genotypes & phenotypes). P1 Generation: Two parents bred from heterozygous breeders A & B with ≥80% accuracy (16 – 19 correct genotypes & phenotypes) P1 Generation: Two parents bred from heterozygous breeders A & B with ≤80 % accuracy (15 or less correct genotypes & phenotypes) P1 generation forms four offspring for the F1 generation. F1 for F2. F2 for F3. All genotypes and phenotypes are 100% accurate. P1 generation forms four offspring for the F1 generation. F1 for F2. F2 for F3. All genotypes and phenotypes are ≥80% accurate. P1 generation forms four offspring for the F1 generation. F1 for F2. F2 for F3. All genotypes and phenotypes are ≤80% accurate.
