A farmer wants to breed a variety of taller corn. a) How can the farmer use variation in the height of the current corn plants to produce taller corn plants? b) Will the farmer's work be most effective if height in corn plants is determined by polygenic inheritance, multiple alleles, or co-dominant alleles? Explain. c) The farmer finds that many of the tallest corn plants are also very susceptible to a particular disease. How could the farmer design an experiment to find out if the genes for height are linked to the genes for resistance to the disease?
A farmer wants to breed a variety of taller corn.
a) How can the farmer use variation in the height of the
current corn plants to produce taller corn plants?
b) Will the farmer's work be most effective if height in
corn plants is determined by polygenic inheritance,
multiple alleles, or co-dominant alleles? Explain.
c) The farmer finds that many of the tallest corn plants
are also very susceptible to a particular disease. How
could the farmer design an experiment to find out
if the genes for height are linked to the genes for
resistance to the disease?
d) If these genes are linked, what steps could the farmer
take to create a breed of corn that is taller and more
disease-resistant than the current corn crop?
