Answer Key for Genetics Practice Problems 2
Here is the detailed answer key for Genetics Practice Problems 2. Each question is followed by a step-by-step solution to help you understand the reasoning behind the answers.
Question 1: What is the probability that two heterozygous parents (Aa) will have a child with the genotype AA?
Answer: The probability is 25%. This is because the possible genotypes for the offspring are AA, Aa, and aa, each with a 25% chance.
Question 2: In a dihybrid cross, what is the phenotypic ratio of the offspring?
Answer: The phenotypic ratio is 9:3:3:1. This ratio is derived from the four possible phenotypes resulting from the combination of two traits.
Question 3: What is the role of DNA in genetics?
Answer: DNA (Deoxyribonucleic Acid) is the molecular structure that carries genetic information. It is responsible for the transmission of hereditary characteristics from parents to offspring.
Question 4: Explain the concept of genetic linkage.
Answer: Genetic linkage refers to the tendency of genes that are located close together on a chromosome to be inherited together. This phenomenon is crucial in understanding the inheritance patterns of linked genes.
Question 5: What is the significance of the Hardy-Weinberg equilibrium in genetics?
Answer: The Hardy-Weinberg equilibrium is a principle that describes the genetic equilibrium in a population. It states that the frequencies of alleles in a population remain constant from generation to generation in the absence of evolutionary forces.
