VEGIE PEOPLE PRAC

VEGE PEOPLE PRAC AIM: · To construct a vegetable child by choosing genes for eyes, arms, feet, hair, and gender from Ma Onion and Pa Potato

Table 1: Genetics of the Vegetable People

Table 2: Ma and Pa have the following Characteristics

Answers

·Complete five (5) punnet squares for the possible genotypes of the offspring of Ma and Pa (eyes, arms, feet, hair and gender). ·Complete the probability of each characteristic Put Ma’s allele’s on the top and Pa’s down the side

METHOD: ·Select a gene for each trait from Ma and Pa (choose 1 gene from each envelope) ·Then combine the gene pairs together to form genotype and phenotype of your vegetable child (Table 3). Table 3: The Genotype and Phenotype of my Vegetable Child

METHOD: · Use the appropriate materials (refer to table 1) to construct and name your vegetable child.

METHOD: · Conduct a class survey to identify the frequency of each trait within the class (Table 4).

Table 4: Class totals for each characteristic

·Although many of the children produced by the class had the same phenotypes, no two vegetable children were EXACTLY the same. Explain why this is so.

·In this experiment, there are 162 genetically different vegetable people possible. Use the results of this experiment to explain why there are infinite variations possible in a species that reproduces sexually, such as humans. 3 possible genotypes for eyes BB, Bb or bb X 3 possible genotypes for arms etc. x 3 possible genotypes for feet etc. x 3 possible genotypes for hair etc. x 2 possible genotypes for sex XX or XY 162
