What is the characteristic of non-allelic interaction?
Non-allelic interaction occurs between two alleles of the same gene.
Non-allelic interaction is also known as genetic recombination.
Non-allelic interaction involves the interaction between genes located on different chromosomes.
Non-allelic interaction only occurs in prokaryotic organisms.
Non-allelic interaction, also known as epistasis, refers to the interaction between genes that are not alleles but are located on different chromosomes. These genes can influence the expression of each other, leading to modified phenotypic ratios. This type of interaction can result in different patterns of inheritance, such as dominant or recessive epistasis. Hence, option 3 is correct.
The explanation for the incorrect options :
Option 1 is incorrect because allelic interaction refers to the interaction between different alleles of the same gene, not different genes.
Option 2 is incorrect because genetic recombination refers to the process of creating new combinations of genetic information by exchanging DNA segments between homologous chromosomes during meiosis, and is not related to non-allelic interaction.
Option 4 is incorrect because non-allelic interaction can occur in both prokaryotic and eukaryotic organisms.
