2. To calculate 2pq when q = 0.2, we first need to understand the concept of hardy-weinberg equilibrium, where p and q are allele frequencies, and p + q = 1. Here, p represents the frequency of the dominant allele, and q represents the frequency of the recessive allele. Step 1: Recall the given information, p + q = 1, and q = 0.2. Step 2: Solve for p: p = 1 - q = 1 - 0.2 = 0.8 Step 3: Calculate 2pq: 2pq = 2 * 0.8 * 0.2 = 0.32 3. To determine if acquired traits can be inherited, we need to understand the difference between acquired traits and genetic traits. An acquired trait is a characteristic that an organism develops during its lifetime due to environmental factors or experiences, while a genetic trait is determined by an organism's DNA. Step 1: Understand the difference between acquired traits and genetic traits. Step 2: Recall that acquired traits are not passed on to offspring because they are not part of the organism's genetic material. Only genetic traits, determined by DNA, can be inherited.
