A Student Proposes That Left-Handedness Is a Recessive Trait and Is

question 7

Multiple Choice

A student proposes that left-handedness is a recessive trait and is hidden in much of the human population.A survey of his class of 36 students finds that 9 students are left-handed.Using the Hardy-Weinberg formula,what would be the expected allelic and genotypic frequencies in this theoretical population?

• A)P =.27 q =.09;
• P² =.07,2pq =.048,q²=.00479
• B)P =.5 q =.5;
• P² =.25,2pq =.50,q²=.25
• C)P =.75 q =.25;
• P2 =.56,2pq =.25,q2=.25
• D)They cannot be estimated using these limited data.

Definitions:

Delayed Reinforcement

A scenario in which a reward does not immediately follow the desired action, which can affect the strength and persistence of learning.

Partial Reinforcement

A conditioning method where a response is only occasionally rewarded, leading to more resilience in the learned behavior.

Continuous Reinforcement

A learning principle where every instance of a desired behavior is reinforced, leading to rapid acquisition of the behavior.

Immediate Reinforcement

The instant reward following a specific behavior, intended to increase the likelihood of that behavior being repeated.
