Which of the following events can result in inheritable genetic variations in organisms?
translation errors during protein synthesis
mutation of DNA by environmental factors
genetic recombination during meiosis
occurrence of viable errors during DNA replication
All of the events listed can result in inheritable genetic variations in organisms.
Translation errors during protein synthesis: Errors during translation can lead to changes in the amino acid sequence of proteins, which can result in altered phenotypes and inheritable genetic variations.
Mutation of DNA by environmental factors: Mutations can occur in DNA due to exposure to various environmental factors such as radiation or chemicals. These mutations can lead to genetic variations that can be passed on to future generations.
Genetic recombination during meiosis: During meiosis, genetic material is shuffled and exchanged between homologous chromosomes, which leads to genetic recombination and the creation of new combinations of alleles. This process can generate inheritable genetic variations.
Occurrence of viable errors during DNA replication: Errors can occur during DNA replication, leading to changes in the DNA sequence. These errors can introduce genetic variations that can be inherited by offspring.
