Observing human phenotypes and probability in genetics Name: _________________________ Purpose Reinforce concepts of simple genetics by examining the following: Genotype Phenotype Homozygous Heterozygous Dominant Recessive Materials Mirror Objectives Determine your phenotype for ten different traits. Determine your possible genotypes for the ten different traits. Evaluate your uniqueness as an individual. Part A- Determining your phenotype and genotype In part “A” you will examine your phenotype, or appearance, and will draw conclusions about your genotype, the gene combinations that determine appearance....

Human Mendelian Traits Mendelian Traits are those traits which follow Mendel's rules of only 2 possible versions of a gene(1 dominant, 1 recessive). There are only a few examples of this in humans. 1. Circle the heterozygous dominant genotypes: AA Aa aa YyYY W Re RR 2. Circle the homozygous recessive genotypes: AA Aa aa YyYY V ir Rr RR 3. Use the chart below to determine your phenotype (observable characteristic) and possible genotype(s) (a pair or pairs of alleles)....

PRE-LAB QUESTIONS - Genetics - Lab #9 1. Humans inherit two alleles for every gene. For an example, gene "R" provides the instructions for face shape. The dominant allele for the gene is denoted as R and the recessive allele for the gene is denoted as r. The dominant phenotype is a round face shape and the recessive phenotype is a square face shape. Use this information to answer the questions below: What is the genotype of a homozygous dominant...
