Navy veteran studies genetic variation - Scientists & Engineers on Sofas (and other furnishings)

The video features a conversation between Maria Zacharias and Amy Batacletti, a veteran and NSF fellowship recipient. Amy discusses her transition from the Navy, where she worked as a Neurographer's Mate, to academia. She explains her research on genetic variation within plant species, focusing on fieldwork and lab processes. The discussion highlights the importance of genetic diversity for species survival, especially in the face of environmental disturbances. The video concludes with well wishes for Amy's ongoing PhD work.

What was Amy Batacletti's role in the Navy?

• Marine Biologist

• Neurographer's Mate

• Meteorologist

• Oceanographer

What is the primary purpose of collecting plant hoppers in Amy's research?

• To study their migration patterns

• To analyze their feeding habits

• To estimate genetic variation

• To observe their mating rituals

How are the insects euthanized in Amy's research process?

• By freezing them

• Using ethanol vapors

• By crushing them

• Using carbon dioxide

What tool is used in the lab to count the insects collected?

• Electron microscope

• Magnifying glass

• Telescope

• Dissecting microscope

What is genetic drift?

• A process of natural selection

• A change in gene frequency due to random sampling

• A method of DNA extraction

• A type of genetic mutation

Why is biodiversity important in a population?

• It provides a range of strengths and weaknesses

• It increases the population size

• It ensures all individuals are identical

• It reduces the need for genetic variation

What could happen to a population with low genetic variation during a disturbance?

• The population will become more diverse

• The population will thrive

• All individuals will survive

• A large part may be wiped out
