Genotype Changes and Selective Pressure

The video tutorial guides students through a card-based activity to understand genetic inheritance across multiple generations. Participants use cards to represent alleles and work with partners to determine genotypes for successive generations. The activity introduces concepts of genetic variation and selective pressure, requiring students to adapt their card decks to reflect changes in genotype. The exercise emphasizes the importance of genetic diversity and survival in changing environments.

What is the initial genotype setup for each team member?

• Big L little l

• Little l Little l

• Big L Big L

• Big L Big L Little l

During Generation 1, what do partners do after shuffling their decks?

• Add a new card

• Flip their top card

• Discard a card

• Exchange cards

How is the genotype for Generation 2 determined?

• By keeping the same partner

• By removing cards

• By finding a new partner

• By adding more cards

What happens if a partner's genotype changes in Generation 2?

• They add more cards

• They reshuffle their deck

• They keep the same deck

• They discard their deck

In Generations 3 and 4, how many times do partners switch?

• Six times

• Five times

• Four times

• Three times

What is the outcome if a genotype of little L little L is flipped during selective pressure?

• It survives

• It is reshuffled

• It is recorded

• It is discarded

What must players do if their genotype changes during the activity?

• Add new cards to their deck

• Exchange cards with another player

• Reshuffle their cards

• Keep the same cards

What is the final step after all generations and selective pressure are completed?

• Exchange all cards

• Start a new game

• Discard all cards

• Return to the teacher for directions

What is the purpose of introducing selective pressure in the activity?

• To make the game more complex

• To simulate natural selection

• To increase the number of cards

• To ensure all genotypes survive

What happens to a genotype that does not survive under selective pressure?

• It is recorded

• It is reshuffled

• It is kept as is

• It is exchanged with another player
