You have to listen to audio episodes that is about 40 minutes(together) Just answer questions according to the discussed topic. Answers should be a paragraph for the very least. Can be more for certain some questions.

RADIOLAB Podcast “Inheritance” Homework Assignment
http://www.radiolab.org/story/251884-leaving-lamarck/#commentlist
http://www.radiolab.org/story/251885-you-are-what-your-grandpa-eats/
SECTION I – “Leaving Your Lamarck” Part 1 (Lamarck, Krammerer & the Midwife Toads)
1. Jean Baptiste Lamarck was a pioneer in the field of biology. He is most famous
for coming up with a
theory to explain how living things change over time. However, his theory
happened to be wrong. Describe Lamarck’s theory and why it is incorrect.
2. Summarize the story of Paul Krammerer and his midwife toads. Specifically, how
does this story relate to the subject of this podcast and to Lamarck’s work.
“Leaving Your Lamarck” Part 2 (Rat Maternal Behavior)
Regarding the experiment with rats that was measuring maternal behavior:
3. What do good rat mothers do to their babies? Are all rats good mothers?
4. How does the care that a rat mother gives her pup impact the kind of mother
female rat pups grow up to be?
5. How do the researchers think this maternal rat behavior is being passed on? Are
the mom’s teaching their pups? Are the moms changing the instructions in the
rat pup’s DNA? Or is it something else? Support your answer. To answer this
question, you must describe the process of gene expression that affects the
maternal behavior of the rat pups. Your answer will involve a discussion of how
the gene is turned on and how the protein is made (gene transcription and
translation).
6. What was turning off the maternal care gene (i.e. What was preventing the gene
from being transcribed and translated)? How did the rat maternal behavior turn
the gene back on?
SECTION II – “Your Are What Your Grandpa Eats” (Population data from Overkalix,
Sweden)
Regarding this analysis of population data:
1. How were the ancestors affected by a boy experiencing starvation between the
ages of 9 – 11?
2. What inheritable effect do they think the boy’s starvation had on his body?
3. How where ancestors affected by a boy being well-fed between the ages of 9 11?
4. What do the researchers think is the difference between the expression of some
genes in the sperm of starving versus well-fed boys?
SECTION III – Regarding the stores on Rat Maternal Behavior and The Population Data
from Sweden.
1. What do you think “epigenome” means? How is it different than the genome?
2. Based on what you learned from these two stories in this podcast, do you think
that your behavior and environment can impact the instructions in your
children’s DNA? On the molecular genetic level, what was altered about the DNA
in the offspring and ancestors in these stories? (You answer should relate to
gene expression.)
