Question

Why do some acquired traits become inherited trait. Like a vegetable or fruit unliked by parent is unliked by offspring

Answer 1

Dear Student ,

RNA interference (RNAi) might be involved in the inheritance of acquired traits. RNAi is a natural process that cells use to turn down, or silence, specific genes. It is commonly employed by organisms to fend off viruses and other genomic parasites. RNAi works by destroying mRNA, the molecular messengers that carry information coded in a gene to the cell’s protein-making machinery. Without its mRNA, a gene is essentially inactive.RNAi machinery exist throughout the animal kingdom, including humans.
Some of character are seen in off spring which is not present in parent this may due to recessive allele combination.
Ex when two heterozygous tall pea plant (Tt) are crossed we get progeny in which short pea plant (tt) is present.
