Inheritance Lab - Essay Example 2. Identify and record your possible genotypes based on your phenotypes. Genotypes are represented using two alleles. Identify the alleles using the letters indicated below (capital letter indicates dominant allele, lowercase indicates recessive allele): 3. Using your possible genotypes, identify and record all of the possible pairings of parental genotypes that could have led to your possible genotypes. Crosses are denoted in this form: FF x Ff and indicates the genotypes of both parents. You should list all of the possible crosses that could lead to your phenotype. Use the chart below to record the observations of your phenotypes and to record your inferences regarding your genotype and all of the possible crossings of parental genotypes that can account for your genotype. Phenotypes are expressed with a single letter related to the trait. Genotypes include both alleles and are, thus, expressed with two letters (one for each allele). Possible parental genotypes and crosses consist of two genotypes crossed. For instance, a freckled person will have a phenotype of F and possible genotypes of FF and Ff. One of the possible parental genotype and crosses is (FF x Ff). Be sure to list all possible parental genotypes in terms of possible crosses. Crosses are denoted in this form: FF x Ff and you should list all of the possible crosses that could lead to your phenotype. It was observed that the presence of a dominant gene in the genotype always led to the expression of the dominant trait, which is seen as the phenotype. In addition, the occurrence of a certain genotype could result from the crossing of several possible parental genotypes. This lab provided knowledge that recessive traits were denoted by small letters while dominant traits were denoted by capital letters. One component of my genotype came from each parent due to
