Smooth (S) is dominant over wrinkled (s). What fraction of the offspring in the
following cross would be homozygous recessive for all gene pairs in the cross:
YyTtss x YyttSs?
Nepenthes distillatoria (the carnivorous pitcher plant) as
a model plant makes the following cross. She proceeds to take a wild type pure-breeding
female pitcher plant trisomic for chromosome 2 and crosses it to a normal diploid male pitcher
plant that is homozygous for a recessive mutation (v) that makes it hungry all the time (the
super hungry mutant). A trisomic F1 plant is then back-crossed to the super-hungry male
parent. From this cross:
A] What is the ratio of normal pitcher plants to those that are super hungry when you assume
that v is located on chromosome 2?
B] What is the ratio of normal pitcher plants to those that are super hungry when you assume
that v is not located on chromosome 2?
a. environment components have a large effect on the expression of the phenotype
b. this phenotype is not multifactorial
c. the genotype is for a single gene
d. the environment is equally important to the phenotype as the genotype
e. the phenotype is multifactorial but the genotype strongly influences the phenotype
