MonsterGeneticsLab [Note:Thetwolabactivitiesallowstudentstoapplytheirknowledgeofsimpleandcomplex genetictraits.Studentsdemonstratehowtheyareabletoapplyandsynthesizewhattheyhave learnedinafunactivity.Ifpossible,allowstudentstoillustratebothparentandchildmonsters basedonthegeneticinformationidentifiedforallthreemonstersduringthelab.] Youhavelearnedaboutmanydifferentpatternsofinheritance.Somearesimpledominantor recessive,asinMendeliantraits.Somearemorecomplex,suchasincompletedominantor codominanttraits.Inthislabyouwillinvestigatehowacombinationofthesegenesworksto createanorganism. Part1Procedure: 1. Flipacointwicetodeterminethegenotypeforeachtraitandrecorditinthedatatable. Heads=allele1,Tails=allele2(Example:ifyouflippedheadstwice,yourmonster willhavetwocopiesofallele1forhisgenotype.) 2. Determinethephenotyperesultingfromtheallelepairforeachtrait. 3. Repeatsteps1‐2foreachtraitandcompletethefemalemonster’sTable1.

Part2Procedure: Thefemalemonster(describedinTable1)and amalemonster(seeTable2below)plantohave babymonsters.Theyareinterestedinfindingout for each traittheprobabilitythat their offspringwillhave that trait. 1.
