Genetic Diversity and the Irish Potato Famine

The video discusses the importance of meiosis and genetic diversity, using the Irish potato famine as a case study. It explains how the lack of genetic diversity in potatoes led to widespread crop failure due to blight, resulting in famine and mass immigration. The video highlights the agricultural practice of monoculture and its risks, contrasting it with the benefits of genetic diversity. It also draws parallels to human genetic diversity and disease resistance, emphasizing the importance of variation in surviving diseases.

What is the main biological process discussed in relation to the Irish Potato Famine?

Why were potatoes considered beneficial to the Irish population before the famine?

• They were a luxury food

• They were highly nutritious

• They were used as currency

• They were easy to store

What was the traditional method of planting potatoes?

• Cloning the best potato

• Using potato seeds

• Planting potato flowers

• Using potato leaves

What is the main disadvantage of the monoculture cloning method?

• It produces smaller potatoes

• It leads to genetic uniformity

• It takes longer to grow

• It requires more labor

What is the significance of meristematic tissue in potatoes?

• It gives potatoes their flavor

• It helps potatoes store nutrients

• It allows potatoes to grow from cut pieces

• It makes potatoes resistant to blight

What disease affected the potatoes during the Irish Potato Famine?

• Mildew

• Wilt

How does genetic diversity help in disease resistance?

• It ensures some individuals survive

• It prevents disease spread

• It makes all individuals immune

• It eliminates the need for treatment

Which of the following is an example of genetic diversity in humans?
