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
Put Ma’s allele’s on the top and
Pa’s down the side
·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
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.
