Solution and Explanation
Step 1: Universality of Genetic Code
The genetic code is universal, meaning that it is the same across all living organisms, from bacteria to humans. This ensures that the same set of codons produces the same amino acids across species.
Step 2: Redundancy of Genetic Code
The genetic code is redundant, meaning that multiple codons can encode the same amino acid. For example, both UUU and UUC codons specify the amino acid phenylalanine.
Final Answer: Two characteristics of the genetic code are: 1. Universality 2. Redundancy

- A rare genetic disorder resulting from homozygosity for a recessive allele (\( r \)) occurs in 2 out of every 10,000 individuals in a population. Assuming that (i) the disorder is not lethal, (ii) the disorder does not impact reproductive success, (iii) no new mutations are introduced in the population, and (iv) the population follows Hardy-Weinberg equilibrium, the percentage (%) of the carriers in the population that pass the \( r \) allele to offspring is ..........
